Email: Configuring Outgoing Mail Server (SMTP)
April 12, 2006
Adding an email account in cPanel is simple, but sometimes configuring your email client to receive email can throw you for a loop. The reason? There isn’t one set way to do it. What will work for you might not work for me and it all rests on choices made by your ISP.
In an effort to reduce junk mail and spam, a growing number of ISPs have implemented outbound email SMTP port controls. If this is true of your ISP, then if you are not hosting your website with them, but are using a separate company, your hosting mail server will not be able to send outgoing email using the same settings you use for your Incoming Mail Server (POP3).
Instead, you can send outgoing mail messages by converting your Outgoing Mail Server (SMTP) to use your ISP’s mail servers. The Incoming Mail Server (POP3) does not need to be changed.
Configuring Email: Using ISP’s Outgoing Mail Server Setup
The images below indicate how to configure an email account using Microsoft Outlook, 2002 to receive email, but the configuration applies across email clients.
If setting up the email client to send/retrieve mail for www.domain.com, you would use the Incoming Mail Server (POP3) setting: mail.domain.com
However, the Outgoing Mail Server (SMTP) setting, as stated above, will vary depending on your ISP. Ours is smtp.sbcglobal.yahoo.com, and WILL NOT WORK if set it up as mail.domain.com. See image below.

In addition, you must click on ‘More Settings’ and change your Outgoing Mail Server (SMTP) settings to your ISP account’s SMTP settings.
Just so you know, they should match the settings for your personal ISP account.
This is how it would be set up:

Configuring Email: Using Host’s Outgoing Mail Server Setup
If your ISP does not require that you convert your Outgoing Mail Server (SMTP) settings to their mail servers, then setting up the email client to send/retrieve mail for www.domain.com is basic; you would use the same setting for both your Incoming Mail Server (POP3) and Outgoing Mail (SMTP): mail.domain.com.
There will likely not be a need to click to ‘Advanced Settings’ or ‘More Settings’ when using your host’s Outgoing Mail Server (SMTP) as the email client will normally default to use the same settings as your Incoming Mail Server. If not, there will be a checkbox (as in the image above).
