[Mailman-Users] postfix hints

[Kevin Crawford]

Hello all - trying to get mailman working with postfix, on RH7.2.
I have seen references everywhere about the error I am getting, but none of
the solutions are panning
out. It is the mail wrapper complains of the GID. I did % python -c'import
os; print os.getgid()' and got the GID of the mailman user and tried to do
the configure, and install but the error just changed to the new GID...if I
change to 99 (nobody) it runs, but didn't take that as the recomended course
of action...
any hints would be appreciated.
thanks,
Kevin
