These things shouldn't be in /etc/postfix/virtual.

This is not a Mailman issue. This is probably fetchmail that is
delivering the message to about-dummy at localhost.

With MTA = 'Postfix'. Mailman will maintain both aliases in
/usr/local/mailman/data/aliases and virtual maps (if necessary?) in
/usr/local/mailman/data/virtual-mailman, but you have issues that will
probably preclude this from working.
If fetchmail is going to deliver to addresses like
LISTNAME at localhost
LISTNAME-bounces at localhost
and localhost is in mydestination as it appears to be, you only need
aliases and not virtual maps.
Thus both what you have in mm_cfg.py and what you have in main.cf looks
If you have mail being given to Postfix for LISTNAME at company.com, you
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['company.com']
in mm_cfg.py and, assuming the list's email domain is company.com (see
my reply to your other post), Mailman will generate virtual maps like
LISTNAME at company.com LISTNAME
LISTNAME-bounces at company.com LISTNAME-bounces
in /usr/local/mailman/data/virtual-mailman and you need to add
hash:/usr/local/mailman/data/virtual-mailman to virtual_maps in
If you actually need multiple domains for the same list in the virtual
maps, Mailman won't do that automatically.
