This can be fixed in one of two ways. You can set


in mm_cfg.py, or you can see
including the part about fix_url under "Existing versus new lists"

No, it's not saying that. It's saying that the group that the mailman
wrapper (/usr/local/mailman/mail/mailman) was *built* to expect to be
run as is not the group that the MTA is running it as.

Basically, there are two ways to fix this as indicated in the message.
You can change the mail server's configuration file so it runs as
group "mailman" or you can change the wrapper so it expects to be
started by group "daemon". The second option is better than the first
because Mailman's security depends on the wrappers being setgid and
only setting group "mailman" after they've determined that things are

The standard way to accomplish the latter when installing from source
is to re-run configure, providing the command line option
`--with-mail-gid=daemon' just as the message says and then rerun "make
install". I don't know how to do it when installing from a Gentoo
