is rumored to have said:
Postfix default of the maximum queue lifetime is 5 days:
https://www.postfix.org/postconf.5.html#maximal_queue_lifetime
One month is very long, but I usually see systems to retry for at
least three days to cover outages of MTAs that cannot be solved within
a few hours or for example happen on a weekend. Not all MTAs are run
by enterprises with 24/7 staff availability.
5 days has been a widespread norm since the core of the Internet was
academic and traditional business organizations where you could
reasonably expect an outage starting on Friday night would not even be
noticed until Monday morning. I'm pretty sure my first IDA/KJS Sendmail
machine had a 5-day queue lifetime, as I had no clue how to change
it...
backup-mx ? :)
should at that time have being 6 to 60 days, more or less, else it would
not be a backup-mx, but yes sendmail do have most core settings same as
todays postfix core
