we are using scalix so far without any big issues.
Today it happened the first time that we could not send out a mail. Investigating at the logfiles it turned out that the mailserver is requesting a TLS encryption which our server fails (sendmail). I looked at the internet (and Scalix pages) but mostly it is discussed how to set up the local (Scalix) server to encrypt mails form a user and not how to set up sendmail in case of relay.
The following happened:
Code: Select all
Aug 18 11:24:43 server1 sendmail[31396]: n7I9OIiu031396: from=<xyz@ettex.de>, size=12502, class=0, nrcpts=1, msgid=<H0000068000127a2.1250587457.server1.ettex.de@MHS>, proto=ESMTP, daemon=MTA, relay=localhost [127.0.0.1]

I looked around and found the following info on the sendmail webpages: http://www.sendmail.org/~ca/email/auth.html. However this is nor really solving my issue (I believe) as this is only a setup if you always use the same ISP.
Any ideas where to look at or what to do to overcome this limitation?...
Thanks!
