Upgraded to 4.4.0 and now I see the following in the log:
[27982] [Thu Jun 16 16:59:19 2016] [warning]: Can’t set DBI::db=HASH(0x8b3efb0)->{PrintWarm}: unrecognised attribute name or invalid value at /usr/local/lib64/perl5/DBI.pm line 739, line 473. (/usr/local/lib64/perl5/DBI.pm:739)

RT is acting normally but these warnings keep on appearing in the logs. Not sure what to make of it.
I want to make sure I clean this up before continuing with my configuration as I have a “separate/relay” mailserver.

This suggests that you’d customized RT’s code directly, so I bet you are running a 4.2-era (or older) /Ticket/Update.html file against RT 4.4. In other words, RT has made changes to that file as part of your upgrade to 4.4.0, but your local override is hiding those changes, so that’s why you’re seeing strange errors.

The way to proceed (in descending order of preference) would be to refactor your customizations to be callbacks, which is the recommended way to customize RT’s templates, or simply remove your local override if you don’t need it, or finally apply your customizations again to 4.4’s version of /Ticket/Update.html.

See Writing extensions - RT 5.0.5 Documentation - Best Practical for more detail on the recommended approach.

Thanks,
