I'm using fetchmail to feed mailman3 and am having a problem with the postfix hooks. My list name is llllllllll@ddddddddd.net. However, fetchmail passes the email to lllllllllll@localhost. So I am getting this error in the mail log:
Out: 550 5.1.1 <llllllllll@localhost>: Recipient address rejected: User unknown in local recipient table
Is there something I need to add to mailman's recipient table, fetchmail or an alias in postfix?
You have probably configured Postfix per https://docs.mailman3.org/en/latest/install/virtualenv.html#setup-mta which is based on https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.ht....
The issue is the postfix_lmtp file referred to in transport_maps and local_recipient_maps only have addresses in the ddddddddd.net domain.
I think you can solve this by instead adding 'localhost' as an alias domain for the ddddddddd.net domain and configuring Postfix per https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.ht...
