Outgoing Mail Problems

Is anyone else having this problem with sending outgoing mail? Even if I try the online squirrelmail, I get errors after it times out. (squirrelmail gives me ‘document contains no data’. And when I send with Thunderbird, it sits at “sending message - 1%” until it times out and says my smtp server might not be configured correctly.

I literally can’t send any email!

Is your smtp server configured correctly?

For example, I send mail through my ISP. I receive it through DH.
