    I am trying to figure out why SSL is not working for my setup when I try to send email via a 3rd party application, such as Thunderbird. TLS and regular smtp through port 25 work perfectly, but whenever I try to use SSL on port 465, the port is open, I get a smtp server connection error.

    I have used the Perfect Debian Sarge howto found in the howto directory, great howto by the way ;) Any help is apprecieated in this puzzleing problem :S

    Confused as can be,

    Plaese have a look at the mail log. (/var/log/mail.log) if you get any errors there when you connect on port 465.

    Nothing appears inside any of the mail logs when I try to connect :S Odd, you think something might appear...

    I checked:
    /var/log/mail.err
    /var/log/mail.info
    /var/log/mail.log
    /var/log/mail.warn

    On a side note, how would I regenerate the SSL certificates to change the owner from "localhost" to "mail.my_domain.com" ?

    Is it maybe your firewall that blocks accesses to port 465?

    I made sure that the port is open, it was blocked the first time I tried it, but it turned out not to be the issue :S

    Here is the result of "netstat -tap"

    There's nothing running on port 465...

    I thought The Perfect Setup - Debian Sarge (3.1) guide also setup a ssl smtp connection ?

    How would I go about setting up a SSL connection for smtp ? Also how would I go about changeing the certificate owner, currently it reads:
    When I retrieve my e-mail through a pop3 or imap SSL connection.

    No, it's a TLS connection that uses port 25.

    You can use TLS by telling your email client to use a secure connection.

    To create other TLS certificates, simply re-run the steps from the tutorial.
    To create new POP3/IMAP certificates, have a look here: http://www.howtoforge.com/forums/showthread.php?t=1168

    Thanks :) The post you pointed me too solved the certificate problem :)

    I thought TLS was less secure :S That's why I was asking about the SSL connection.

    No, TLS is secure. :)
