It's probably my misunderstanding on the reject_rbl_client syntax but if
I use the following reject_rbl_client configuration , the mail logs
tells me that the reject_rbl_client syntax is invalid:
reject_rbl_client example.com=[127;128].0.0.1
I use this as a restriction in smtpd_recipient_restrictions:
smtpd_recipient_restrictions = permit_mynetworks
reject_unauth_destination reject_rbl_client example.com=[127;128].0.0.1
Upon receiving an email I get the following error in the mail log:
fatal: RBL reply error: missing "]" character
Somehow the [127;128] part is not correct. If I for example change this
to 127.0.0.[1;2] then it works.
Could it be that postfix thinks that [127;128] is an IP address with mx
lookup disabled?
I'm using Postfix 2.9.3
Kind regards,
Martijn Brinkers
