Update to SP2 GW2014 Breaks SMTP Connections

What is potentially going on here? Updated to Sp2 and now Fax Machine, Voicemail server, etc. Cannot connect and send email any longer? Some new security setting? Help please.
See logs:
14:32:21 F360 DMN: MSG 196623 Accepted connection: [192.168.1.111] ()
14:32:21 F360 DMN: MSG 196623 Sending machine verification failed. (KM978DE0)

Re: Update to SP2 GW2014 Breaks SMTP Connections

Solved: Somehow during, or as a result of update, this "Reject if PTR Record Does Not Exist" setting became enabled on the SMTP/MIME Security Settings on the GWIA and was rejecting the messages:

Reject If PTR Record Does Not Exist: Rejects messages from unidentified sources. This setting corresponds with the --rejbs switch.
An unidentified source is defined as a sending SMTP host that does not have a PTR (pointer) record. A PTR record provides the mapping between the hostname and the corresponding IP address of the sending SMTP host. This setting lets you reject messages if the sending host is not authentic.
When this option is enabled, the GWIA refuses messages from a relay host if a reverse DNS lookup shows that a PTR record does not exist for the IP address of the GWIA’s host.
When this option is disabled, the GWIA accepts messages from any host, but it displays a warning if the initiating host is not authentic.

Hi,

Curious indeed that a setting is potentially changed during an upgrade!

Thanks for letting us know about your experience - that way we all learn.

Cheers,
