Is "mailing" a reserved name as an email prefix?

    Hello,
    I could not find a mention elsewhere, but are there some forbidden names that cannot be used for mail addresses or aliases?
    I am trying to set up a forward "mailing@...", but I keep getting "unknown user". All other entries like "mailring@" do work.
    I need this to forward to a mailman mailing list.

    Help greatly appreciated!

    Gert

    no. Check the /etc/alaises file.

    There is nothing in the aliases file except the usual stuff. The Ispconfig db does contain the entries in the mail_user resp mail_forwarding tables- It is a riddle to me why postfix won't accept them while dovecot does.

    You can not add mailboxes (virtual users) for the server hostname in postfix. Postfix matches everything @server.hostname against Linux shell users and not mailboxes.

    That's why the hostname shall be a subdomain and is never used for mailboxes or websites.

    Sorry I did not explain properly. I added [email protected], which works fine. Adding [email protected] does not work, as does [email protected] etc.
    The server hostname is only what gets expanded in the bounce reply, the error message.
    There is no shell user by that name.

    I'm not sure if I understand you right. The server hostname is "mail5.mycompany.com". The client domain name is "someclient.org". Does what you say imply I cannot set up any virtuser or forward that contains "[email protected]"? Or any prefixes containing "mail*" for any other client domain, at all? I tried postfix debugging but it does not tell me anything more than "The mail system <[email protected]> (expanded from "[email protected]"): unknown user: mailing".
    This would be very unusal, and unlucky indeed.

    No. I just meant that you can not add email addresses like [email protected].
    Search your postfix config if there is something about mailing:

    grep mailing /etc/postfix/*
    grep mailing /etc/aliases

    Nothing in /etc/postfix/*
    The comment for the initial mailman list in /etc/aliases:
    "## mailman mailing list" (I had added it following an outdated howto for adding mailman).
    Removed the whole set of mailman aliases, newaliased, restarted postfix. Same behaviour: mailing: unknown user.
