Hello All,
I'm getting rejections showing:
reject: RCPT from unknown[96.92.246.116]: 450 4.7.25 Client host rejected:
cannot find your hostname
But if I do an nslookup on the same box, it does resolve.
I thought this was purely if no reverse exists reject.
I have added this under:

Thanks Viktor.
To confirm, I'm creating the list of valid emails to accept and then
forward and if not in that list reject.
My question would be, will postfix send off a process to query every so
often in order to build the multiple lists, or as each mail is about to be
delivered?

sed on the experience I have had so far, I believe the best most reliable
method is to get the information from the source.

Hello All,
I'm trying to see if someone has a good app to connect to an exchange or
O365 server either via LDAP or AD to grab all of the legitimate email
accounts, forwarding accounts and Groups in order to build a
transport_recipients file this way reject all invalid email prior to
forwarding it

I can't figure out why.
It keeps saying queue write error, but disk & cpu performance is good, disk
space is good.
I also have noticed at times it's when there are multiple recipients on the
message.
