Email Clients and E-mail Protocols - POP3, SMTP, IMAP Tutorial
You can use either the webmail interface or an email client. Check our tutorial on how to use cPanel webmail. If you decide to use an email client, such as Microsoft Outlook Express, MS Outlook, Mozilla Thunderbird and Eudora, here are the settings you need:
Incoming mail server (POP3/IMAP server): mail.yourdomainname.com
Outgoing mail server (SMTP server): mail.yourdomainname.com
Username: the full e-mail address. Example: you@yourdomainname.com instead of you.
Password: Assigned in cPanel -> Email Accounts.
SMTP authentication must be enabled for the login to be successful.
If you have your domain pointed to an external server and the MX record is resolving to one of the Tanatek servers use the server name as the Incoming/Outgoing mail server.
You can also use secure authentication to your mail server.Email ports
The POP3 port for inbound emails is 110 (995 if you want to use secured POP3)
And the IMAP port for inbound emails is 143 (993 if you want to use secured IMAP)
The SMTP port for outbound emails is 25 or 2525 (465 if you want to use secured SMTP)

What is POP3?
Post Office Protocol version 3 (POP3) is a standard mail protocol used to receive emails from a remote server to a local email client. POP3 allows you to download email messages on your local computer and read them even when you are offline.
What is IMAP?
The Internet Message Access Protocol (IMAP) is a mail protocol used for accessing email on a remote web server from a local client. IMAP and POP3 are the two most commonly used Internet mail protocols for retrieving emails. Both protocols are supported by all modern email clients and web servers.
Main difference between IMAP and POP3:
The POP3 protocol assumes that there is only one client connected to the mailbox. In contrast, the IMAP protocol allows simultaneous access by multiple clients. IMAP is suitable for you if your mailbox is about to be managed by multiple users.
What is SMTP?
Simple Mail Transfer Protocol (SMTP) is the standard protocol for sending emails across the Internet. SMTP uses TCP port 25 or 2525 and sometimes you can have problems to send your messages in case your ISP has closed port 25. To determine the SMTP server for a given domain name, the MX (Mail exchange) DNS record is used.
