Hi Barry,

I'm sorry I couldn't write earlier.

The official documentation doesn't explicitly claim it. But there's a
section about setting up virtual domains that doesn't warn that virtual
domain implementation is incomplete:


I, as a seasoned user of Postfix, Apache, and other virtualized server
software, but new user of Mailman, can confirm, that this documentation
made me think mailman fully supports virtual hosting. Unfortunately,
there are other resources on the web that are similarly confusing.

With most of the patches already working, it doesn't look too hard to 
add full virtual domain support to Mailman 2.x via address rewriting. I
fixed more issues on my installation myself.

Any way, I'd be very pleased if the documentation is “fixed”, even if
its brokennes is not obvious to people who have lived with Mailman
for long time.

If Mailman 3 is comming soon, I could stay with the current,
semi-functional state (combination of Mailman 2.x, downloaded patches
and some local fixes) and switch to Mailman 3 when it's ready (possibly
help with bugreports and some fixes, as I know a bit of Python).

Any timelines?
