Postfix Issue

Hello

I have a problem with Postfix / SASL / TLS:

(1) I can receive email just fine using TLS / PLAIN LOGIN

(2) I cannot send email using TLS / PLAIN LOGIN

(3) I can auth myself when I use telnet on the server

Code:

t390:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 t390.greatnet.de ESMTP Postfix (Debian/GNU)
EHLO client.sample.com
250-t390.greatnet.de
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH PLAIN LOGIN
250-AUTH=PLAIN LOGIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
AUTH PLAIN ************
235 2.0.0 Authentication successful
quit

I have no clue what is causing those issues.

 

Any errors in your mail log and auth.log when you try to authenticate?

 

actually now I have achieved making incoming mail as SSL with plain login and outgoing TSL with plain login...

I just can't figure out why the incoming isn't TSL anymore...
