We suggest using the tutorial at THIS LINK for manual configuration of your favorite email program. Click email from the list on the left, and then find your specific question or program.
Here is the most commonly used setup, replace "domain.com" with your actual domain name.
Type:
POP3 (or IMAP if you want to store email server-side)
incoming server:
mail.domain.com
outgoing server:
mail.domain.com
username:
youraddress@domain.com
password:
The password you made in cPanel for the above email account when you created the email account.
Note:
Most email programs default the "username" in the above example as simply "youraddress" which lacks @domain.com, you need to make sure you have the full email address as the username, sometimes called "account name"
Secure Password Authentication:
Off
My Server Requires Authentication:
ON
You may find it necessary to use your ISP's outgoing mail server if you can receive mail, but not send it.
However, before you call them and ask for their SMTP, try changing your SMTP port from the default 25 to 26. This is especially useful for those of you that travel and do not want to use webmail. Using port 26 should allow you to use your laptop and mail program wherever you may travel.
If that does not work, call your ISP and ask them for their SMTP outgoing mailserver and other SMTP settings, and use their SMTP settings even if they contradict our settings recommended above.
More information on how to send email when your ISP blocks port 25, or general "receiving mail but not able to send mail" information can be found at the URL below:
