A while ago we increased group SMTP read and open timeouts
to address issues we were seeing with Gmail sometimes giving
really long timeouts for these values. The commit was:
3e639e4aa7
Now, we want to increase all SMTP read timeouts to 30s,
since the 5s is too low sometimes, and the ruby Net::SMTP
stdlib also defaults to 30s.
Also, we want to slightly tweak the group smtp email job
not to fail if the IncomingEmail log fails to create, or if
a ReadTimeout is encountered, to avoid retrying the job in sidekiq
again and sending the same email out.
