SMTP operates on both port 25 and 587, as some ISPs block port 25. Our SMTP servers do require authentication through SMTP AUTH, and do not support SSL/TLS.
Your outgoing SMTP server is:
Your-domain.com is the domain name that you have a mailbox on. If your email address is email@example.com, your SMTP server will be mail.bobson.com.
To use the SMTP server, you will also need to tell your email client that the outgoing mail server requires authentication.
You may need to specify the username and password for this authentication – simply enter the same username and login as you use for your incoming mail.
Encryption such as SSL or TLS will also need to be disabled in order to connect successfully.
