I used to get the messages that are now being deleted after five days.
Any suggestions?
I would suggest looking at the mailer daemon logs on both the sending
and receiving systems. It would appear that the sending system is
having difficulties at the receiving system end.
You will likely find the root of your issues in the log entries for
that message (or those messages) that occurred over the 5 days in
question.
PS: "Connection timed out with example.com" is the first thing I'd look
at.
