    Hello,

    Playing with mailman and ISPConfig mail conf, I kill my mail !
    I have 3 servers ubuntu 20.04. set up with perfect server tuto
    - ns1.domain.tld is Ispconfig web interface + web server + mail with domain = domain.tld
    - ns2 is mirror of ns1
    - ns3.domain.tld is server with web server + mail

    I create a mailing list on ns3.
    To 'address' my list, I create a mail domain on ns3 called ns3.domain.tld, with DKIM and I insert MX (DNS) in my domain.tld zone...
    As a result I had 2 DKIM in same zone domain.tld
    It doesn't really work, so that I delete all that was attached to ns3.domain.tld...

    But now, it is impossible to send a mail with domain.tld.
    Erreur SMTP (451) : add recipient failure 4.3.0 Temporary lookup failure
    I check with Mxlookup web site, my MX is correct
    'host domain.tld' command gives correct answer
    and resolv.conf contains : nameserver '127.0.0.53'

    I saw in howtoforge that it could be amavis, but, I don't see how I can clean amavis conf...
    I try also to create a new DKIM for my domain.tld

    I saw nothing in mail/error.log

    At the moment, I see re-create all as the only solution...

    Hello,
    I am back ... I have an issue with Firefox : https://www.howtoforge.com/index?register brings me to ERROR404. Chrome works !

    I dig and push mails, I finally discover a error in /var/log/mail.err
    postfix/trivial-rewrite[1910231]: error: open database /var/lib/mailman/data/transport-mailman.db: No such file or directory

    That's normal I uninstall mailman.
    Do you know where can I remove that conf in postfix ?

    Thanks a lot
