Postfix TLS working fine but SSL over port 25 not working
Hello. I have an Ubuntu Server 8.10 with postfix/courier installed. Everything works perfect, pop3 over 110 and 995, imap on 143 and 993, normal smtp and tls smtp on 25 work perfect. The only problem is on ssl smtp over port 25. It just doesn't work. Nor 465 or 587. I will put the postfix config files below:

Here's the relevant section from my master.cf:
smtps inet n - - - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o milter_macro_daemon_name=ORIGINATING If your starttls on the standard port is working, no reason this won't that I know of. - Arch |

Ah, I just realized I probably should have clarified a bit. My config gives me plain-text plus starttls on the standard SMTP port (25) and with the config snippet I posted, I also get SSL on the smtps port (465) but port 25 works the same (plain-text or starttls). - Arch |

oh god do I love you now... :D well...I put you code there and tried on port 465 and now it's working like a charm! :) thank you dude, may the gods bless your soul |
Fantastic. I just spent at least 30 hours changing things and searching for help. Nothing worked.
Just found this and it's perfect. Thanks for the great info. |
Just one more problem. Going to port 465, with SSL and start the session it seems to work, with the correct certificates, but doesn't recognize my password.
If I go to port 25 with TLS everything works. From mail.log: Code:
SASL authentication failure: cannot connect to saslauthd server: No such file or directoryAny idea why my passwords aren't working? |
Got it working by having smtps run un-chroot'd.
Any reason not to do that? |
