Good Morning,

I just finished migrating Mailman from one server to another, following the instructions at URL http://wiki.list.org/pages/viewpage.action?pageId=4030682

I am running Mailman version is 2.1.15

But now I am seeing the following error in my /var/log/maillog "NOQUEUE: reject: RCPT from unknown[]: 550 5.1.1 <external IP Address>: Recipient address rejected: User unknown in local recipient table; from=<d> to=<> proto=ESMTP helo=<[]>"

Here is my postconf -n output:

alias_database = hash:/etc/aliases, hash:/etc/mailman/aliases alias_maps = hash:/etc/aliases, hash:/etc/mailman/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 html_directory = no inet_protocols = all mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, list.$mydomain mydomain = informs.org myhostname = mail.informs.org myorigin = $myhostname newaliases_path = /usr/bin/newaliases.postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES recipient_delimiter = + sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination unknown_local_recipient_reject_code = 550

Here is my mm_cfg.py config file:

DEFAULT_URL_HOST = 'list.informs.org' DEFAULT_EMAIL_HOST = 'list.informs.org'

add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)

MTA = 'Postfix'

Can someone please counsel as to how to correct this error? Thank you, Rose
