Running configure, make and make install will not result in data loss,
but you should stop Mailman before make install and start it after.

If you have local mods to the Mailman code or you made settings in
Defaults.py instead of mm_cfg.py, there can be loss of those things, so
make your settings in mm_cfg.py and if you have modes to running code,
be sure you know what they are so you can reapply them.

Postfix is not the issue in your original post. Your OP referred to a
CGI wrapper group mismatch, not a mail wrapper group mismatch.

You can set the group in Apache with Apache's Group directive, but this
is a global setting. In Apache 2.4, there is also a VHostGroup directive
that applies only to a VirtualHost, but not in older versions. See

For Postfix, if delivery is via aliases, postfix will run the pipe in a
Mailman alias as the user and group of the owner of the aliases.db file
in which the alias is found. Note this is the primary group of the owner
of the file, not the group of the file.
