Can you run

telnet localhost 25

and then type in

ehlo localhost

? Does it show that it supports STARTTLS?

What's in your main.cf?

Falko,

What confuses me is that it works, then stops and then miraculously starts working again, without doing anything???? Could it be client related, on thunderbird?

[falko]

I'm not sure why this happens, but I don't see an error in your Postfix configuration.

[lspdev]

This is driving me crazy!!! Weeks have gone by, been working fine using Starttls... and now, after a server reboot, due from an update, it now does it again..

I can only send email now if I do not use authentication - but even though I try:

root@server:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.

quit
221 2.0.0 Bye
Connection closed by foreign host.


IT expects it.... But NO matter what I try, it does not accept connection with STARTTLS.... WHY WHY WHY???

[lspdev]

An error occurred sending mail: Unable to establish a secure link with SMTP server mail.christiancoalition.co.za using STARTTLS since it doesn't advertise that feature. Switch off STARTTLS for that server or contact your service provider.

Not sure if this is related ... but my root user is getting mails on the sell relating to sqlite...

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/2009062
6/sqlite.so' - /usr/lib/php5/20090626/sqlite.so: cannot open shared object file:

is this related in any way to my problem?

I don't think this is related, but to go sure I'd update your PHP packages.
