Hello list,

I had been running mailman and postfix on the same server. I had to add the following into main.cf to integrate mailman into postfix

alias_maps = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases
recipient_delimiter = +
mailman_destination_recipient_limit = 1

and the mm_cfg.py is as below

DEFAULT_URL_PATTERN = 'http://%s/mailman/'
DEFAULT_EMAIL_HOST = 'list.mydomain.com'
DEFAULT_URL_HOST = 'list.mydomain.com'
MTA = 'Postfix'
POSTFIX_ALIAS_CMD = '/usr/sbin/postalias'
POSTFIX_MAP_CMD = '/usr/sbin/postmap'
DELIVERY_MODULE = 'SMTPDirect'
SMTPHOST = 'localhost'
SMTPPORT = '25'
add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['list.xxxxx.com']
IMAGE_LOGOS = '/mailmanicons/'

Now the mailserver has physically been moved to a different server. How can I inform mailman about my physically moved postfix ? Should I just add the email domain (which this server once had) at the relay_domain section of the postfix running on this very server?

If Postfix continues to run on the Mailman server, make no changes to this Postfix or to Mailman.

If I understand correctly, the issue is that incoming list mail is now routed (via a DNS MX record) to a different server. What to do depends on a few things. Is list.mydomain.com a dedicated domain such that all mail to that domain should be delivered to the Mailman server? Is the Mailman server accessible from the outside world?

If both answers are yes, just make the MX record for list.mydomain.com point to the Mailman server.

If the domain is dedicated, but the server is not accessible from outside, use a transport_maps entry on the mail server to relay all mail to the list.mydomain.com domain to the mailman server.

If both answers are no, you will need to tell the mail server to relay all the list addresses to the Mailman server via transport_maps on the mail server. The FAQ at http://wiki.list.org/x/ZoCj may help you with generating the transport maps on the Mailman server, but they will still have to be updated on the mail server whenever lists are added or deleted on the Mailman server.
