I think this is the main reason why mailing fails so often: Most exit
nodes simply don't allow connecting to port 25. Every time you try
sending a mail and your exit node at that time doesn't allow it, you'll
get the described timeout.

No, Tor is smarter than that: your Tor client knows the exit policies of the Tor servers, and it picks an appropriate exit node.

If I had to pick a reason for your problem, it would be that only 2 of
the 700 currently running Tor nodes allow port 25 to exit, and these
are likely on all sorts of SMTP blacklists.

Is it possible your mail service can use port 587? I don't know how many exit nodes allow that (nor do I know how to quickly check), but I'm using 587 with SMTP over SSL, and it seems to work fine. Check my headers if you don't believe me. :-)
