Description Phil Stracchino (Unix Ronin) 2018-04-06 14:31:53 UTC

Postfix runs mailman scripts as user nobody, as it should.  However, mailman 2.1.24 and 2.1.26 (at least, possibly older versions as well) configure mailman with --with-mail-gid=280.  This results in a group mismatch error when Postfix tries to deliver mail to a Mailman list:

Apr  6 06:41:19 minbar Mailman mail-wrapper: Group mismatch error.  Mailman expected the mail wrapper script to be executed as group "mailman", but the system's mail server executed the mail script as group "nobody".  Try tweaking the mail server to run the script as group "mailman", or re-run configure,  providing the command line option `--with-mail-gid=nobody'.


If mailman is manually reconfigured after 'ebuild configure' with --with-mail-gid=nobody, everything works again.  I'm not sure what the best method is for the other option, configuring postfix to run mailman as group mailman.

#19257, #106403 and #568582 are related.
