[Mailman-Users] Mailman+Exim in Ubuntu

[Odhiambo Washington]

Hello Barry,

I was able to resolve this, using the Ubuntu package itself, so I do not
need to manually compile.
But it also gave me the impetus of learning how to manually compile stuff
in Linux .

Now that MM21 is running, I need help running MM3 alongside it and migrate
from 2.1
The main purpose of getting this particular VM was to get to run MM3.

For now, I think I am taking a sabbatical from MM2 list, headed to MM3
mailing list to seek support of someone willing to hand hold me with that
monster.
