Re: TLS not being advertised or not running?

* Theodore Durst tdu...@durstmedia.com:
  I think I have a configuration issue, but it looks like a strange one
 on this end. Before going line by line, I thought I would throw this out
 to the list.
 
 I am attempting to set up postfix (send only) with TLS support. TLS was
 compiled in and postfix does run, it does send mail in the clear.
 However, we need it to send via TLS. I am wondering if there is a line
 in main.cf that tells postfix to advertis/offer TLS authentication that
 is not set. Is there a command to ask postfix if TLS is running?

postconf -n

The tutorial, while useful, is nevertheless dated.

The sending site doesn't offer/advertise TLS; only the 
receiving site can do that.


Your sending site won't initiate TLS if the receiver doesn't 
offer it.  Also note that some network security devices, 
notably PIX, will interfere with TLS and other SMTP features.


If the command
# postconf smtp_tls_security_level
shows anything other than unknown parameter, then TLS 
support is compiled into postfix.





Like I said above, this sounds like something is amiss with one of the
config files, but I am not sure where to look.

Any hints?



Here's the docs for enabling TLS while sending mail:
http://www.postfix.org/TLS_README.html#client_tls
http://www.postfix.org/TLS_README.html#client_tls_levels
http://www.postfix.org/postconf.5.html#smtp_tls_security_level
