Q: I cannot send emails to another user under my domain name.
After upgrading to SmartMail, you will find that you can no longer send emails from a "@yourdomain.com" email address to another email address within the same domain using your POP email client.
The SmartMail system has increased security features to help combat spam and it considers any email sent within the same domain from a POP email client that is not using a "mail.yourdomain.com" SMTP setting as "spoofed" email. These "spoofed" emails will be rejected and will not be delivered.
To ensure that emails sent within the same domain from a POP email client are delivered, please adjust your POP email client settings as follows:
Change your outgoing SMTP server setting to: mail.yourdomain.com
Change your outgoing SMTP port number to 587
Set "my server requires authentication"
To set server authentication:
Tool -> Account... -> 'mail' tab -> Select mail account -> properties -> 'Server' tab -> check 'My server requires authentication' -> Click 'OK'
