Hello,
I'm using two instances of postfix and lately I've been getting a lot of
deferred email, any suggestions how to stop accepting email that can't be
delivered. I do have local recipients table, server should not accept email
that can't be deliver. Please help!
host# perl check_outmail
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
