It affects every address in /var/lib/mailman/data/virtual-mailman. If
you didn't see the effect on all addresses, it's because you didn't
run bin/genaliases after setting VIRTUAL_MAILMAN_LOCAL_DOMAIN.

I don't understand. If you just don't set VIRTUAL_MAILMAN_LOCAL_DOMAIN
at all, i.e.accept the default setting of None, no domain information
at all is appended to the "to" addresses. If this is not what you see,
leave it out of mm_cfg.py and run bin/genaliases and look at the
result after genaliases.

Here's an example.

In mm_cfg.py I have

MTA = 'Postfix'
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['grizz.org', 'msapiro.net']

The beginning of data/virtual-mailman has (with comments removed)

mailman-loop at grizz.org  mailman-loop
mailman-loop at msapiro.net        mailman-loop
gpc-website at grizz.org              gpc-website
gpc-website-admin at grizz.org        gpc-website-admin

This tells Postfix that the virtual address mailman-loop at grizz.org maps
to the address mailman-loop, the virtual address
mailman-loop at msapiro.net maps to the address mailman-loop, the virtual
address gpc-website at grizz.org maps to the address gpc-website, the
virtual address gpc-website-admin at grizz.org maps to the address
gpc-website-admin and so forth.

These "to" addresses are unqualified so Postfix treats them (assuming
the default append_at_myorigin = yes) as though they are @$myorigin or
(again assuming the default) @$myhostname. This should be a locally
deliverable domain so that the corresponding aliases

mailman-loop: /var/lib/mailman/data/owner-bounces.mbox
gpc-website:             "|/usr/local/mailman/mail/mailman post
gpc-website-admin:       "|/usr/local/mailman/mail/mailman admin

are effective for those addresses.

If for some reason in your Postfix configuration, myorigin is set to
some value which is not a locally deliverable domain, you then need to
append a domain to the "to" addresses in virtual-mailman. This may be
localhost or some other domain. For example. if you set


then all the "to" addresses in virtual-mailman become like

mailman-loop at grizz.org  mailman-loop at localhost
mailman-loop at msapiro.net        mailman-loop at localhost
gpc-website at grizz.org              gpc-website at localhost
gpc-website-admin at grizz.org        gpc-website-admin at localhost

The intent is to add qualification so they become local addresses if
the bare name is not understood to be in a local domain.

If bare names such as mailman-loop, gpc-website, gpc-website-admin, etc
are understood to be local, VIRTUAL_MAILMAN_LOCAL_DOMAIN should be set
to None (the default). If not, VIRTUAL_MAILMAN_LOCAL_DOMAIN should be
set to one and only one of the domains in Postfix's mydestination

That's because

VIRTUAL_MAILMAN_LOCAL_DOMAIN = 'list.example.com', 'others.domain.com',

is not valid Python, and even if you were to make it a valid list like

VIRTUAL_MAILMAN_LOCAL_DOMAIN = ['list.example.com',
'others.domain.com', etc.domain.com]

It would make no sense.
