I finally tracked this down. There is an ASSP bug here. Here's what is happening:
My Exchange server had TLS enabled on the connector that ASSP was connecting to, so when EHLO was sent to the Exchange server it responded with the following: 250-mail.eatough.net Hello [192.168.0.240] 250-SIZE 10485760 250-DSN 250-ENHANCEDSTATUSCODES 250 STARTTLS 250-AUTH 250-8BITMIME 250-BINARYMIME 250 NOOP I do not have TLS enabled on ASSP yet, so it changes this response to: 250-mail.eatough.net Hello [192.168.0.240] 250-SIZE 10485760 250-DSN 250-ENHANCEDSTATUSCODES 250 NOOP 250-AUTH 250-8BITMIME 250-BINARYMIME 250 NOOP The NOOP in the middle of the capabilities list is seen as an end of that list by the sending server, so it starts sending the MAIL FROM, and the rest of the responses now come back to the sending server in an order it doesn't understand. ASSP should not replace the "250 STARTTLS" with "250 NOOP" -- it should be dropping that line completely.

I'm running on Windows Server 2008, ActiveState Perl 5.8.9 Build 825. With 13.02 mail comes in just fine, as soon as I upgrade to either 14.02 or 14.05 mail starts bouncing. I have two ASSP servers at different sites, this repros on both machines. Any additional logging I can provide to help narrow down what's going on here?
