I have successfully installed and configured postfix and mailman and everything works correctly. The server FQDN is lists.example.com. My problem is that I would like mails sent to subscribers to appear as if they came from email@example.com instead of firstname.lastname@example.org?
My system details are: postfix 2.9.6 mailman 2.1.14 Ubuntu 12.04
Here is the most significant part of the postfix configuration (/etc/postfix/main.cf):
myorigin = /etc/mailname myhostname = lists.example.com mydomain = example.com alias_maps = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases alias_database = hash:/etc/aliases #mydestination = lists.example.com, lists, localhost.example.com, localhost mydestination = $mydomain $myhostname localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all home_mailbox = Maildir/ inet_protocols = all mailman_destination_recipient_limit = 1
