I'm far from a Postfix expert, and I'm not sure what's going on in your
case. My understanding is that with virtual_mailbox_domains, mail to
such a domain is always delivered to a mailbox or mail directory, and
aliases such as those which pipe the mail to a mailman wrapper do not
apply. So, I'm not sure what you have that enables this mail to be
delivered to Mailman.

The above is sufficient and (almost) correct if laughingboot.net is a
local (non-virtual) domain as far as Postfix is concerned. Yhe last
line should be

POSTFIX_STYLE_VIRTUAL_DOMAINS = ['gurgitate.org']

POSTFIX_STYLE_VIRTUAL_DOMAINS is a list even if it has only one entry.

If /etc/postfix/virtual is a virtual_alias_maps file, the first line
above says laughingboot.net is a virtual_alias_domain and is not
required if laughingboot.net is listed explicitly in
virtual_alias_domains in main.cf. The second line says all mail to the
domain laughingboot.net should be routed to mail.laughingboot.net.

If it is a virtual_mailbox_maps file, The first line may work
analogously, but I'm not sure and the second line specifies a mailbox
name to which to deliver laughingboot.net mail.
