[Mailman-Users] mailman on CentOS, with virtual domain configuration for Postfix

[David Hláčik]

Hi,
ive fixed the problem by changing owner of aliases, and virtual-mailman
files to apache:mailman, the problem is , that postfix is now having problem
to sending message :
in postfix maillog i see :

Nov 23 14:16:15 sx2 Mailman mail-wrapper: 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: "apache". 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=apache'.
