[Owasp-board] Possible hosted Mailman solution - response requested

I found out that OSL (Open Source Labs) does hosting of many open source
project's Mailman lists as a service offering.  
I reached out to them to see if they could host lists.owasp.org. I've
heard back and they are willing and able to host our Mailman lists. The
high-leve stuff is:
(1) They use a shared platform for all their Mailman lists so we _may_ need
to rename some lists during the migration.
(2) I do not have a cost for this yet. OSL generally works on a cost
recovery basis. I'd guest-imate ~$180/month or ~$2,200/year.
(3) I am tempted to ask if its possible to get a individual host for this
and pay extra so that we have an isolated Mailman instance. This would
avoid the multi-tenant instance of Mailman and some of the wrinkles around
hosting multiple domains with Mailman. Alternately, I could see if they'd
manage a host running at Rackspace.
Please provide your feedback on the items above ASAP. I am planning on
responding to OSL this evening / tomorrow AM to get more details and see
about possible migration dates.
Here's the thread between OSL and myself:

We can do this. What we need from you is an archive of your mailing lists.
which point you should queue up all messages sent in, and then after I have
mailing lists set up, switch the mx records over to:
Additionally you can make a pointer record to
In order to use the web interface.
And then you can forward the queued up mail onto us, and it should all be
assuming you can have a small down time for the mailing lists. I have an
window to do this tomorrow around 2-5 PST, if that works for you. Or we can
it later as well. It should take ~1 hour or so to get everything set up on
end, including regenerating the archives into our mailman setup.
One last thing of note: Mailman doesn't handle multiple virtual domains
particularly well, and we run a rather large shared instance of mailman.
the issues is that internally mailman doesn't use fully qualified list
and such one can have a list name conflict across domains. E.g
general at lists.osuosl.org and general at lists.owasp.org would both be referred
as 'general' internally, and both couldn't exist.
As a result we name all mailing lists as $project-$list at lists.$project.org,
then use postfix rules to funnel mail to $list at lists.$project.org ->
$project-$list at lists.$project.org. This works quite well, with the one side
effect of end-users occasionally seeing the $project-$list at lists.$
address on mail sent out from our mailing list server.
Assuming you have a default install of mailman, all the data we need is in
/var/lib/mailman, so you can just tarball that up and send it our way and we
can handle the rest (aside from DNS record changes after the lists are in
Let me know if you have any questions/concerns, etc.
