Email notifications broken in 12.5

[EWTHeckman]

I just upgraded from Retrospect 11.5 to 12.5 today. One problem I immediately noticed is that once again, email notifications have stopped working. (They worked only rarely in 11.0, and had finally become mostly reliable in 11.5.)

 

The first failure message I saw says "No server found at that address (-597)" which is clearly not true since it was working just before the upgrade.

 

After digging around the forums, I found notes that disabling the SSL feature should fix the problem, but attempting to do so leads to an "Invalid response from SMTP server (-592)" error.

 

I captured the TCP communications between my Retrospect Server machine and the mail server. Here they are, sanitized for privacy:

As you can see, Retrospect is definitely communicating with my mail server.

Is there a solution to this?

[kleeberg]

I am having the same problem and have found that toggling the SSL on and off only changes the failure message to an error -530 unlike what EWTHackman saw. I have tried several different mail servers, the one on the server (using the name and 127.0.0.1) and on other boxes by name and IP with the same results. Solutions?
