When these 2 values differ, in my case, say
mail.yourdomain.tldvsyourdomain.tld, a bounce loop occurs.I use ZeptoMail as a relay, and this quickly shot my email count up, which especially for the limits they impose, not being that great.
When those emails bounce, the bounce notification comes back addressed to
@mail.yourdomain.tldin this case.There was no transport rule for that domain set, so instead of delivering, it sends it back out through the relay, which bounces it again, infinitely.
I added POSTFIX_FQDN to the transport map which seems to have stopped the bounces from happening.
