What you are seeing is expected bevahior. Thunderbird (like most modern mail clients) supports the newer TLS protocol while most Microsoft mail clients support the older SSL wrapped port (SMTPS) approach on port 465. Setup for this is described here:
http://www.postfix.org/TLS_LEGACY_README.html#server_enable You will see that there is an SMTPS line in your master.cf that is by default commented out. This is by design. If you are going to be doing much with Postfix, there are a lot of options, so you might want to get a book about it. Personally, I recommend "The Book of Postfix". -- Postifx setup documentation does not specify removing the chroot for SMTP Auth https://bugs.launchpad.net/bugs/105378 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
