Good morning,
Questions:
How does the secondary MX know to transport to the primary when it is back
online? (some online “guides” talk about editing transports, but the postfix
documentation does not)
The emails remain in the queue on the backup mx and postfix (in)frequently tries to delive

Good morning,
I have a stable low-volume Postfix setup on a 10-year-history IP address. In
mid-2025 we need to relocate interstate. The mail MX is going to be offline for
a few days for the relocation and have possible further outage time through new

only if you have 25 or fewer users.
I thought this means a user can send an e-mail to 25 users max at once?
