IO::Socket::SSL 1.31 should be good (better is 1.32 or above) - this 
module is only wrapper around the SSL-stuff to make it more easy to handle 
SSL-connections
more important is  Net::SSLeay (1.35 - or higher) and the installed SSL - 
librarys (OS or OpenSSL)

The Exchange issue could be also related to the usage of selfcert 
certificates (on your site). Some mail servers try to verify the 
certificate of the connected server, this behavior is not recommended but 
some times it is used this way.

Betreff:        [Assp-test] SSL enabled and Exchange



Anybody have any issues crop up with inbound mail from an Exchange 
server and SSL being enabled on ASSP?

We're currently running under Linux:

ASSP Version: 1.7.5.2(1.0.06)


Module for SSL:

IO::Socket::SSL       1.31

I'm getting daily notices from users of mailing not being received, the 
ASSP log entries shows that it was accepted it, made a copy of the 
message to /assp/notspam, but it never was received at the mail server.

Setting up an entry in noTLSIP for any failing server fixes the issue. 
It's gotten to the point that I just shut it off.

Mail server logs (Zimbra, a.k.a Postfix) show there was a connection 
that matches the ASSP logs time/date stamp, and then a disconnect.

Every time I've asked the remote admin what mail server, they've 
confirmed Exchange.  This last one was Exchange 2007.

Suggestion?

Doug
