Multimail 3.1.

Set SMTP to, with ESMTP turned on and set to port 25.

I get a Time Out when I try to send a message. Receiving is fine.

If I turn off ESMTP, I get a message saying I need to authenticate.

Trying gives a similar problem.

Multimail seems the best IMAP program I've tried, but not without being able to send!

Your advice appreciated.
