The matter of where the spool is is actually a red herring. It is
irrelevant to the problem or the solution. The spool is local
storage for _delivered_ email. Mailman doesn't have anything to do
with mail that's already been delivered. It has everything to do
with being a place that mail is delivered TO.
So, more simply you have the following:
and you don't want to cahnge that. If you were willing to change
that the easiest approach would likely be to run a webserver on
HostA under a virtual hostname of say lists.domain giving:
HostA runs an MTA but has no web presence.
HostB runs a web server but has no MTA.
lists.domain (really HostA) runs a web server and Mailman.
Howeverm if you don't want to do that, you can still use Mailman as
Install Mailman on HostA (the one with no web server).
Make all the edits on hostA for Mailman that have to do with mail
delivery (alias file edits etc).
ObNote: I strongly recommend that you configure your MTA to
auto-detect and support Mailman lists without requiring alias file
edits. I know such recipes have been developed for Exim (the MTA
I use, http://www.exim.org/howto/mailman.html), and I believe
similar has been done for Postfix and Sendmail. (Ask here).
NFS export the Mailman directory heirarchy to HostB (the web server)
Configure the web server on HostB exactly as if Mailman were
Edit ~mailman/Mailman/Defaults.py such that:
DEFAULT_HOST_NAME points to HostA
DEFAULT_URL points to your installation on HostB.
DELIVERY_MODULE is SMTPDIRECT
SMTPHOST points to HostA
Mail comes into the lists on HostA, the MTA delivers it to
mailman, it gets broadcast.
The web interface (including moderation and all that) runs on
HostB but operates on and modifies the files on Host A. In the case
of moderation Mailman processes run on HostB that deliver mail
without a local MTA to HostA for delivery.
Its a little fiddly, but Mailman is specificaly architected to
support such configurations.
