first I'm using the F14 pre-compiled packages of both Exim and mailman. according to what I can find mailman expects its scripts to be executed by the group "mailman" with the GID of 41. I have set the following in Exim which I thought would cover this requirement. /etc/group shows the GUI of mailman as 41 as so does the /etc/passwd file. When I send a message to the mailing list I get back the following error - Group mismatch error. Mailman expected the mail wrapper script to be executed as one of the following groups: [mail, postfix, mailman, nobody, daemon], but the system's mail server executed the mail script as group: "exim". Try tweaking the mail server to run the script as one of these groups: [mail, postfix, mailman, nobody, daemon], or re-run configure providing the command line option: '--with-mail-gid=exim'. Any help or pointers would be appreciated. Thanks, Jeff ---- from exim.conf file --- MAILMAN_HOME = /usr/lib/mailman MAILMAN_WRAP = MAILMAN_HOME/mail/mailman # User and group for Mailman, should match your --with-mail-gid # switch to Mailman's configure script.
