Thank for all, now I have the file like that: in /etc/aliases majordomo: "|/usr/lib/majordomo/wrapper majordomo" majordomo-owner: admin@domainname lista: "|/usr/lib/majordomo/wrapper resend -l lista" lista-outgoing: :include:/var/lib/majordomo/lists/lista lista-request: "|/usr/lib/majordomo/wrapper majordomo -l" lista lista-approval: owner-lista owner-lista-outgoing: owner-lista owner-lista-request: owner-lista owner-lista: admin@domainname It's OK? I have make "postalias /etc/aliases" and "postfix reload" like you said. I have send a message to majordomo like to: majordomo@domainname subject: body: writeconfig lista passwordlist but majordomo doesn't run, nothing in /var/lib/majordomo/lists directory. The log file /var/lib/majordomo/Log file is empty. The e-mail has arrived to the majordomo mailbox on /var/spool/imap/users/majordomo. Nothing returned to me. I think the alias is never executed. Some idea? What you mean with alias_maps = hash:/etc/aliases and alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases I have to remove one of this?
