This is a known issue. In the old Seamonkey, if you chose to use authentication or encryption in your POP/SMTP connections and the server didn't support it, Seamonkey silently fell back to unencrypted/unauthenticated mode and did the connection anyway. The new Seamonkey 2 doesn't do that -- if you ask for higher security and the server doesn't provide it, it simply doesn't connect. I didn't see the discussion, but I believe that this change was introduced for one or both of the following reasons: (a) The old setup gave users a false sense of security -- they enabled the "security" options believing their traffic was protected, when in fact it was not. (b) The new setup makes it a little bit harder to spoof your mail servers (by a virus, for example), since the spoofer will have to provide compatible security features as well. The old way the spoofer could use a very basic server with no security and it would fool Seamonkey. So, you should go to the "settings" window for your SMTP connection and untick the "Use name and password" box for it. As an aside: I would worry about your ISP allowing non-authenticated use of the SMTP server -- that's what's known as an "open relay", a thing that spammers love. If spammers begin routing crap through it, the server could be blacklisted -- and then, regular users like you wouldn't be able to send messages. There are some alternate ways to keep spammers from SMTP servers -- such as restricting the sender IP or demanding a successful POP connection before allowing the SMTP send -- but I have noticed that most ISPs that used those alternate means have switched to password authentication. I suppose that those alternate means must have shortcomings... I can imagine a couple, and there are probably more. -- MCBastos This message has been protected with the 2ROT13 algorithm.
