After upgrading to SmartMail, you find you can no longer send emails from one "@yourdomainname.com" email address to another using your POP email client.

The SmartMail system has increased security features to help combat spam. Any email that is sent from a POP email client that is not sent using the outgoing mail server "mail.yourdomainname.com" will be considered a 'spoofed' email and will bounce.

To correct this issue please adjust your POP email account settings as follows:
- Change the outgoing SMTP server setting to mail.yourdomainname.com
- Change the outgoing SMTP port number to 587

In Outlook and Outlook express, the outgoing port number can be found in the "Advanced Settings" area.

You need authentication in order to send out any emails on our mail server. Please make the following changes to your account settings.

Tool -> Account... -> 'mail' tab -> Select mail account -> properties -> 'Server' tab -> check 'My server requires authentication' -> Click 'OK'
