Question 1

How do I set up SPF, DKIM and DMARC?

Accepted Answer

Open Email Deliverability in cPanel, click Manage next to your domain and install the suggested DKIM and SPF records, then add a _dmarc TXT record in Zone Editor starting with p=none. Test at mail-tester.com and move DMARC to quarantine, then reject, once SPF and DKIM pass consistently.

Question 2

Email not sending or receiving: the troubleshooting checklist

Accepted Answer

Check, in order: MX records and Email Routing, mailbox quota, ports and encryption (465, 587, 993, 995), the password, then Track Delivery in cPanel for the exact error. Most email failures are one of these; if Track Delivery shows a blacklist or a server-side rejection, open a ticket.

Question 3

How do I create a professional email signature?

Accepted Answer

Keep the signature to your name, title, company, one phone number in international format and your website, in four or five short lines. Add it in Outlook under Settings > Signatures, in Gmail under Settings > General > Signature, and in cPanel webmail under Settings > Identities, then test it on a phone.

Question 4

How do I set up email forwarding and autoresponders?

Accepted Answer

In cPanel open Forwarders under Email and click Add Forwarder to send a copy of one address to another, and open Autoresponders to add an automatic reply with a utf-8 character set and a stop date. Do not set a catch-all default address, because spammers guess addresses and fill the mailbox.

Question 5

How do I fix a full or over-quota mailbox?

Accepted Answer

Open Email Accounts in cPanel to see which mailbox is full, then delete the largest messages in webmail and empty Trash, Junk and Sent, because deleted mail only frees space once the folder is emptied. Raise the mailbox quota only if the hosting account still has free disk space.

Question 6

What is the difference between POP3 and IMAP?

Accepted Answer

IMAP keeps mail on the server and syncs every device, so read and deleted status matches everywhere. POP3 downloads mail to one device and by default removes it from the server. Use IMAP on port 993 for multiple devices; POP3 on 995 suits a single machine only.

Question 7

How do I migrate my email to a new provider?

Accepted Answer

Recreate the mailboxes at the new provider, copy the messages with an IMAP transfer while both sides are live, then change the MX records only after the copy is verified. Run a second sync of the Inbox a few days later to collect mail that reached the old server during propagation.

Question 8

How do I add an email account to Outlook and Apple Mail?

Accepted Answer

Take the secure SSL/TLS settings from cPanel under Email Accounts > Connect Devices, then add the account manually as IMAP: port 993 for incoming and 465 or 587 for outgoing, with the full email address as the username. Manual setup is more reliable than letting the client guess.

Question 9

How do I stop spam reaching my inbox?

Accepted Answer

Turn on Spam Filters in cPanel, lower the spam threshold score, send flagged mail to a Spam folder rather than deleting it, then add filters and a blocklist for the senders that still get through. Never leave a catch-all address enabled.

Question 10

Someone is sending spam from my account, what now?

Accepted Answer

Change every mailbox and cPanel password immediately, look for the compromised script or plugin that is sending the mail, remove attacker-created forwarders and filters, ask support to clear the mail queue, then request removal from the blocklists.

Question 11

How do I use webmail?

Accepted Answer

Open yourdomain.com/webmail, sign in with the full email address and its password, then use Roundcube to read and send mail. Webmail is best for occasional access from any device; a desktop client is better for daily use and offline work.

Question 12

How many email accounts can I create and what is the quota?

Accepted Answer

The number of mailboxes and the storage per mailbox come from your plan. Read the exact figures in cPanel under Email Accounts and on your plan page, and watch usage before a mailbox fills up.

Question 13

How do I create a group or department email like sales@ or support@?

Accepted Answer

You have three ways to run an address like sales@yourdomain.com: a forwarder that copies every message into the team's existing inboxes, a real shared mailbox with its own login and archive, or a mailing list that fans one message out to many members. Small teams usually start with a forwarder and move to a shared mailbox once they need one history everyone can search.

Question 14

How do I export or back up my emails?

Accepted Answer

The reliable way is to connect the mailbox over IMAP in a desktop client such as Thunderbird or Outlook, let it download every folder, then export to a file you keep on your own computer. Webmail on its own is not a backup, because it shows the same server copy that a mistake or a deletion would remove.

Question 15

What are MX records and how do I read them?

Accepted Answer

An MX record tells the internet which server receives email for your domain. Each record has a hostname and a priority number, and the lowest number is tried first. If your MX records point at the wrong place, or at two providers at once, incoming mail stops arriving even though your website works normally.

Question 16

How do I stop my contact form emails from disappearing?

Accepted Answer

Set the form to send from an address on your own domain, put the visitor's address in the Reply-To field instead of the From field, and send through SMTP rather than the PHP mail function. Then turn on form logging so a lost message is still recorded in the site even when delivery fails.

Question 17

What are my email server settings? IMAP, POP3 and SMTP

Accepted Answer

Use mail.yourdomain.com for both incoming and outgoing mail: IMAP on port 993 with SSL, POP3 on port 995 with SSL, and SMTP on port 465 with SSL or 587 with STARTTLS. The username is always the full email address, and cPanel prints the exact values on the Connect Devices page.

Question 18

How do I set up my business email on iPhone?

Accepted Answer

On iPhone open Settings, Mail, Accounts, Add Account, then Other and Add Mail Account, and enter the mailbox details. When the automatic check fails, choose IMAP and type mail.yourdomain.com for both incoming and outgoing with your full email address as the username.

Question 19

How do I set up my business email on Android?

Accepted Answer

In the Gmail app tap your avatar, Add another account, then Other, and choose Personal IMAP. Enter mail.yourdomain.com as both the incoming and outgoing server, port 993 for incoming and 465 for outgoing, and use the full email address as the username.

Question 20

How do I use my business email inside Gmail?

Accepted Answer

In Gmail open Settings, Accounts and Import, add the mailbox under Check mail from other accounts using POP on port 995, then add the same address under Send mail as using SMTP on port 465. Always make sure replies leave from the business address, not your personal Gmail.

Question 21

How do I change or reset an email password?

Accepted Answer

Log in to cPanel, open Email Accounts, click Manage next to the mailbox, type a new password and save. Then update the password on every device and app that uses that mailbox, otherwise they keep retrying the old one and can get the connection blocked.

Question 22

What does my email bounce back mean?

Accepted Answer

A bounce is the receiving server telling you why it refused your message. Codes starting with 4 are temporary and will retry on their own, codes starting with 5 are permanent and need a fix, and the sentence after the code names the real reason.

Question 23

I receive email but cannot send it, what do I do?

Accepted Answer

Receiving works and sending fails almost always because of the outgoing side: a blocked port, the wrong port and encryption pair, or outgoing authentication switched off. Send a test from webmail first, then set SMTP to port 587 with STARTTLS or 465 with SSL and tick that the outgoing server requires authentication.

Question 24

Why does my email go to junk instead of the inbox?

Accepted Answer

Filters judge four things about you as a sender: whether your domain is authenticated with SPF, DKIM and DMARC, what the message contains, who you sent it to, and how people have reacted to your mail before. Fix authentication first, because it is the only part that is pass or fail.

Question 25

What are the hourly email sending limits and why do they exist?

Accepted Answer

Every hosting provider caps how many messages an account can send per hour, to keep one compromised mailbox from ruining delivery for everyone on the server. Your own limit is shown on your plan page and in the client area, and bulk sending belongs on a dedicated sending service, not on a normal mailbox.

Question 26

What is the difference between an email alias, a mailbox and a forwarder?

Accepted Answer

A mailbox is real storage with its own password and its own login. An alias is an extra address that delivers into an existing mailbox and has no password of its own. A forwarder sends a copy of each message on to another address, which may be outside your domain.

Question 27

How do I set up a catch all address in cPanel?

Accepted Answer

In cPanel open Default Address, choose the domain, and pick either Discard with an error to the sender or Forward to a mailbox you own. Forwarding everything catches typos, but it also collects every spam message aimed at addresses that do not exist, so use it only for a short period.

Question 28

Why do my emails disappear from one device but not another?

Accepted Answer

One of your devices is using POP, which downloads messages and then removes them from the server, so the other devices never see them. Check the account type, turn on leave a copy on the server as a stopgap, then convert the account to IMAP so every device mirrors the same mailbox.

Question 29

How do I archive old email to free up mailbox space?

Accepted Answer

Find which folders use the most space, move old messages into a local archive in Outlook or Thunderbird, verify that every message opens from the archive, and only then delete them from the server. Moving mail between folders inside the same mailbox tidies it but does not free any space.

Question 30

How do I delete an email account safely?

Accepted Answer

Export the messages to a local archive first, decide where future mail to that address should go, then delete the mailbox in cPanel under Email Accounts, Manage. Once deleted the messages are gone and new mail to that address bounces back to the sender unless you create a forwarder with the same name.

Question 31

How do I set up my business email in Thunderbird?

Accepted Answer

Read the exact server names, ports and encryption for that mailbox from its Connect Devices page in cPanel, then add the account in Thunderbird with your name, address and password and correct anything the automatic probe gets wrong. Choose IMAP if you use more than one device.

Question 32

How do I create rules and filters to sort my incoming email?

Accepted Answer

Create the rule on the server in cPanel Email Filters, or in Global Email Filters for every mailbox, so it applies on every device at once. Rules made inside Outlook or Thunderbird only run while that program is open on that computer.

Question 33

Why is webmail slow or not loading?

Accepted Answer

Test webmail in a private window and on a second device first: that separates a browser problem from a mailbox problem. If it is slow everywhere, the usual causes are a mailbox at its size limit or a single folder holding tens of thousands of messages.

Question 34

How do I block a specific sender or a whole domain?

Accepted Answer

Add the address or domain to the blocklist in cPanel Spam Filters, or write a rule in Email Filters that files it into a folder. Neither stops the message being received or counted against your mailbox size, and blocking a whole domain eventually catches mail you wanted.

Question 35

How do I check whether my domain is on an email blacklist?

Accepted Answer

Check the sending IP, the domain and the links inside your messages against a blacklist lookup service, because the remedy differs for each. Fix the cause first, then request removal from the list operator, who sets its own process and timing.

Question 36

How do I read my DMARC reports?

Accepted Answer

Aggregate DMARC reports are daily compressed XML files from each receiving provider, holding authentication results for every message that claimed your domain and no message content. Read them to separate your own unlisted senders from real forgery, and tighten the policy only after your legitimate senders pass.

Question 37

Why do some emails arrive minutes or hours late?

Accepted Answer

Late mail is usually held at one hop: greylisting, a queue retry after a temporary rejection, a scan of a large attachment, a forwarding chain, or a mail app that only checks on a schedule. The message headers timestamp every hop and are the only way to see which side was slow.

Question 38

How do I make my website send email through SMTP?

Accepted Answer

Create a dedicated mailbox on your domain, take its exact host, port and encryption from Connect Devices in cPanel, and set the site to authenticate with the full address as the username. Then send a real test and confirm in the headers that the message authenticated.

Question 39

Why can I not send a large attachment?

Accepted Answer

The limit that applies is the smallest one on the path: your app, your server, every hop, and the recipient's server and mailbox. Attachments are re encoded for transit and travel about a third larger than on disk, which is why a file under the limit is still refused.

Question 40

How do I switch from POP3 to IMAP without losing mail?

Accepted Answer

Copy the mail already on your computer before you change anything, then add IMAP as a second account beside the POP one, copy the old messages up into it, confirm they show in webmail on another device, and only then remove the POP account.

Question 41

How do I change MX records and email routing in cPanel?

Accepted Answer

Save the current records, change MX in Zone Editor, then set Email Routing to Remote so cPanel stops delivering locally. Leaving routing on Local is why mail appears to vanish after an MX change.

Question 42

How do I move from a free Gmail address to a business email?

Accepted Answer

Create the mailbox on your domain and prove it sends and receives, import the old mail, update every service that holds the old address, then forward the old address for a transition period before retiring it.

Question 43

Which email addresses should my business create?

Accepted Answer

Create role addresses for anything customers write to: info, sales, support, billing, careers, plus postmaster and abuse. Use free aliases where one person answers, a shared mailbox once two must, and give every published address a named owner.

Question 44

How do I read an email header to trace a problem?

Accepted Answer

Read the header from the bottom up, because each server adds its Received line on top and the oldest hop is last. Then check the time gap between hops, the authentication results, the real From address behind the display name, and the return path.

Question 45

Why does the wrong name show when I send email?

Accepted Answer

The name your recipients see is the display name saved inside the mail app or webmail identity that sent the message, not on the server, so every device can carry a different one. Fix it in the app that actually sent the mail, check the sender identity, and note that a recipient who saved you under an old name keeps seeing it.

Question 46

How do I run email for several domains in one place?

Accepted Answer

Three shapes work: several domains on one hosting account each with its own mailboxes, aliases from several domains landing in one mailbox, or one hosted suite organisation with several domains added. Choose by asking whether the addresses belong to one person or to different people, then set up sending as each address and authenticate every domain.

Question 47

How long should my business keep its email?

Accepted Answer

There is no single answer, because retention rules differ by country and by industry and change over time, so anything with legal or tax consequence belongs with your accountant or lawyer. Decide by category rather than by age, archive instead of deleting when you are unsure, and keep the archive off the mail server.

Question 48

How do I keep my website here and my email somewhere else?

Accepted Answer

The website is found by the A record and the mail by the MX records, so the two can live in different places on the same domain. Point MX at the mail provider, set the hosting account's mail routing to Remote, include the provider in SPF, and publish the provider's DKIM key.
