The lack of the virtual host definition in Postfix would have no effect
on whether or not Mailman creates the virtual-mailman file. Mailman
creates virtual-mailman if and only if there is a list or lists with a
host_name that matches one of the POSTFIX_STYLE_VIRTUAL_DOMAINS

This is strictly a web server configuration issue. it has nothing to do
with virtual-mailman which affects only Postfix.

You can delete lists with Mailman's bin/rmlist, but you don't need to.
Once you get mm_cfg.py correct, you can run bin/genaliases to create
virtual-mailman. If you make changes to DEFAULT_EMAIL_HOST, you may
first need to run

  bin/withlist -l -r fix_url mailman

to fix the mailman list's host_name.

>>> DEFAULT_URL_HOST   = 'mailman.htt-consult.com'
>>> DEFAULT_EMAIL_HOST = 'mailman.htt-consult.com'
>>> VIRTUAL_HOSTS.clear()
>>> POSTFIX_STYLE_VIRTUAL_DOMAINS = 'mailman.htt-consult.com'

Did you make the above change to POSTFIX_STYLE_VIRTUAL_DOMAINS? If not,
that explains the lack of virtual-mailman.
