Hmm, so I guess my plan of running mailman on a tiny mipsel-based router
will not succeed :(
Right now, with a mail and web servers it uses about 12 MB RAM, I just
had hope ~20 MB RAM would be far enough for mailman.
But it seems that without a fair amount of hacking, it won't be possible
(or even it won't be possible at all).
Anyone knows some lighter list archivers (if I just want to display
messages from a mailing list via a web interface, sorted by months,
years etc.)?
