FAQ
Hi, Mark,
Maybe i am wrong but I think something is not correct and I am still
confused.

Let roll back to the beginning stage before Mailman installed. My mail
server using mysql as backend to handle virtual domain. Let say I have
domain1 and domain2 exist. I also have user table in MySQL. For example:
user1 at domain1.com, tester at domain1.com... (for now let's just focus on
domain1.)

So far my mail server handles mail correctly. I sent an email to
tester at domain1.com, postfix use "relay=virtual":
/Aug 9 13:47:33 mail postfix/virtual[2501]: B34C642F01CA:
to=<tester at domain1.com>, relay=virtual, delay=1.5,
delays=1.3/0.06/0/0.06, dsn=2.0.0, status=sent (delivered to maildir)/

Then, as you recommended, I add domain1.com as mydestination on main.cf,
reload Postfix:
/[root at mail postfix]# postconf -n | grep mydestination
mydestination = mail.domain1.com, domain1.com, localhost,
localhost.localdomain/

Then I test by sending email to the same tester at domain1.com, maillog shows:
/Aug 9 13:55:21 mail postfix/local[2751]: 1953942F01CE:
to=<tester at domain1.com>, relay=local, delay=2.2, delays=2.1/0.03/0/0.03,
dsn=5.1.1, status=bounced (unknown user: "tester")/

What I see now is Postfix no longer looking for virtual domain. In
stead, it try to deliver the mail use /"relay=local"/. Since I don't
have a real tester user account on the server, so Postfix failed to deliver.

All above has nothing to do with Mailman. I was configuring and testing
Mailman then suddenly I realized my email server is broken. So I
restored the system (I have a clonezilla image backup) and did the above
test.

Is this means that I should not put "domain1.com" in "mydestination="?

Your list domain 'mydomain.com' is now local per the above.

DEFAULT_URL_HOST = 'mail.mydomain.com'

add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)

MTA = 'Postfix'
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['mydomain.com']
Thus, the above is unnecessary. It causes Mailman to create
virtual-mailman which isn't referenced in your Postfix config anyway.
The fact that you added 'mydomain.com' to mydestination in Postfix
makes it a local domain to Postfix.

The virtual-mailman* files aren't needed or used.

The above is intended to be used in virtual_alias_maps in Postfix if
mydomain.com is a virtual_alias_domain, but it is not. It is a local
domain in Postfix so this isn't needed

Remove

POSTFIX_STYLE_VIRTUAL_DOMAINS = ['mydomain.com']

from mm_cfg.py and remove the data/virtual-mailman* files as none of
that is needed/used by Postfix.
