    I recently migrated servers from centos7/ispconfig3.1x to centos8/3.2
    largely successful (read prior issues) - and mailman is operational as far as accessing the lists and doing the functions.
    BUT - I cannot send out any posts to [email protected] (the address that used to work just fine!)
    I get
    now we have various suspects:
    in /etc/mailman
    Code:
    -rw-r--r--    1 root root        0 Dec 27 10:11 aliases
    -rw-r--r--    1 root mailman 12288 Dec 27 10:11 aliases.db
    -rw-r--r--.   1 root mailman  4498 Dec 27 09:31 mm_cfg.py
    -rw-r--r--    1 root root     4498 Dec 27 09:31 mm_cfg.py~
    -rw-r--r--.   1 root mailman 14103 Nov  3 15:29 sitelist.cfg
    drwxr-sr-x.  42 root mailman  4096 Nov  3 15:29 templates
    -rw-r--r--    1 root root        0 Sep 29 19:23 virtual-mailman
    -rw-r--r--    1 root root    12288 Oct 18 14:16 virtual-mailman.db
    -rwxr-xr-x    1 root mailman   152 Oct 18 14:16 virtual_to_transport.sh
    -rw-r--r--    1 root root      152 Oct 18 14:16 virtual_to_transport.sh~
    aliases and virtual-mailman are both zero length.
    in /var/lib/mailman/data:
    Code:
    drwxrwsr-x. 2 root    mailman  4096 Dec 27 09:35 .
    drwxrwsr-x. 6 root    mailman    79 Nov  3 15:29 ..
    lrwxrwxrwx  1 root    mailman    20 Sep  1 12:13 aliases -> /etc/mailman/aliases
    -rw-r-----  1 root    mailman 12288 Dec 27 09:36 aliases.db

    -rw-r--r--  1 root    mailman 12288 Dec 27 09:31 virtual-mailman.db
    the virtual-mailman is still 0, the transport-mailman contains:

    Code:

    # screw it up, you're on your own.
    #
    # Note that you should already have this virtual domain set up properly in
    # your Postfix installation.  See README.POSTFIX for details.

    in my /etc/mailman/mm_cfg.py:

    #-------------------------------------------------------------

    DEFAULT_URL_HOST   = 'ns10.cdbsystems.com'
    #-------------------------------------------------------------
    # Required when setting any of its arguments.
    add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)
    
    #-------------------------------------------------------------
    # The default language for this server.
    DEFAULT_SERVER_LANGUAGE = 'en'
    
    #-------------------------------------------------------------
    # Iirc this was used in pre 2.1, leave it for now
    USE_ENVELOPE_SENDER    = 0              # Still used?
    
    #-------------------------------------------------------------
    # Unset send_reminders on newly created lists
    DEFAULT_SEND_REMINDERS = 0
    
    #-------------------------------------------------------------
    # Uncomment this if you configured your MTA such that it
    # automatically recognizes newly created lists.
    # (see /usr/share/doc/mailman/README.Exim4.Debian or
    # /usr/share/mailman/postfix-to-mailman.py)
    # MTA=None   # Misnomer, suppresses alias output on newlist
    
    #-------------------------------------------------------------
    # Uncomment if you use Postfix virtual domains (but not
    # postfix-to-mailman.py), but be sure to see
    # /usr/share/doc/mailman/README.Debian first.
    MTA='Postfix'
    POSTFIX_STYLE_VIRTUAL_DOMAINS = ['theeldestgeek.com', 'toptechva.com']
    I believe this was migrated off the old server.
    all looks more or less correct apart from the virtual-mailman and aliases??
    in /etc/postfix/main.cf
    I have lines:
    alias_maps = hash:/etc/aliases
    and alias_database = hash:/etc/aliases
    further down:
    virtual_alias_domains = proxy:mysql:/etc/postfix/mysql-virtual_alias_domains.cf
    virtual_alias_maps = hash:/etc/mailman/virtual-mailman, proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, proxy:mysql:/etc/postfix/mysql-virtual_alias_maps.cf, proxy:mysql:/etc/postfix/mysql-virtual_email2email.cf
    virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf
    virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf
    transport_maps = hash:/var/lib/mailman/data/transport-mailman, proxy:mysql:/etc/postfix/mysql-virtual_transports.cf

    so - any ideas?

    Also I note that when I created a new mailman list TEG in ispconfig - NO entry was made in ANY file! no trace of TEG.
    but it gave no error.
    When ispconfig creates a new mailman list what files are altered in what folders?

    inquiring minds and all that!
    happy holidays to all :)

    I don't use mailman nor centos, but what version of postfix do you have (and/or what do you have for 'enable_original_recipient' setting)? If it's 'yes', try changing to 'no' temporarily and test if mailman works (note it might cause other issues with delivery, but test if mailman is affected).

    post is version 3.31. enable_original_recipient is set to yes, but I remember some problems getting it to work before under ispconfig 3.11, and I'm sure THATS not the problem. something to do with the virtual_domain setup and [email protected] triggering the list, but I dont remember THAT exactly!

    I've been looking back over the centos 8 perfect server which I used
    https://www.howtoforge.com/tutorial...stfix-dovecot-and-ispconfig/#-install-mailman

    and surely the mailman installation instructions are missing a LOT???
    it mentions putting the mailman stanza into /etc/aliases (not /etc/mailman/aliases).
    --snip--
    ## mailman mailing list
    mailman: "|/usr/lib/mailman/mail/mailman post mailman"
    mailman-admin: "|/usr/lib/mailman/mail/mailman admin mailman"
    mailman-bounces: "|/usr/lib/mailman/mail/mailman bounces mailman"
    mailman-confirm: "|/usr/lib/mailman/mail/mailman confirm mailman"
    mailman-join: "|/usr/lib/mailman/mail/mailman join mailman"
    mailman-leave: "|/usr/lib/mailman/mail/mailman leave mailman"
    mailman-owner: "|/usr/lib/mailman/mail/mailman owner mailman"
    mailman-request: "|/usr/lib/mailman/mail/mailman request mailman"
    mailman-subscribe: "|/usr/lib/mailman/mail/mailman subscribe mailman"
    mailman-unsubscribe: "|/usr/lib/mailman/mail/mailman unsubscribe mailman"
    --snip--
    but NO reference in postfix main.cf or master.cf to aliases (and certainly not /etc/aliases???)
    no virtual domains no nothing. arent we missing a LOT of the install instructions???

    ENLIGHTENMENT - at least a work around:

    Playing around a good bit and recreating some of the additional steps in centos 7 server that were missing from centos 8. I've reached an interesting situation.

    Ispconfig3 cannot create any mailing list. when I make a new one, no file appears altered anywhere!
    but the /usr/lib/mailman/bin/newlist infact makes new lists.
    they seem to alter 3 sets of files:
    in /var/lib/mailman/data entries are made in
    aliases (which I symlinked to /etc/mailman/aliases)
    and transport-mailman (not symlinked).
    there is a file virtual-mailman in /var/lib/mailman/data which is NOT altered!
    back in /etc/mailman we see that the file virtual-mailman is altered (and does not affected in the var/lib/mailman/data folder).

    newlist does create the aliases.db via a call to newaliases, but does NOT create virtual-mailman.db or transport-mailman.db! so those have to be created manually
    with postmap /etc/mailman/transport-! (or the lists dont work of course).
    /etc/postfix/main.cf contains:

    alias_database = hash:/etc/aliases and
    virtual_alias_maps = hash:/etc/mailman/virtual-mailman, proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf,
    proxy:mysql:/etc/postfix/mysql-virtual_alias_maps.cf, proxy:mysql:/etc/postfix/mysql-virtual_email2email.cf

    as well as

    transport_maps = hash:/var/lib/mailman/data/transport-mailman, proxy:mysql:/etc/postfix/mysql-virtual_transports.cf

    in /etc/mailman/mm_cfg.py:
    # Default domain for email addresses of newly created MLs
    #was DEFAULT_EMAIL_HOST = 'ns10.cdbsystems.com'
    DEFAULT_EMAIL_HOST = 'theeldestgeek.com'
    #-------------------------------------------------------------
    # Default host for web interface of newly created MLs
    #DEFAULT_URL_HOST = 'ns10.cdbsystems.com'
    DEFAULT_URL_HOST = 'lists.theeldestgeek.com'
    #-------------------------------------------------------------
    # Required when setting any of its arguments.
    add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)
    --
    as well as later:
    MTA='Postfix'
    POSTFIX_STYLE_VIRTUAL_DOMAINS = ['lists.theeldestgeek.com','theeldestgeek.com', 'toptechva.com']
    VIRTUAL_MAILMAN_LOCAL_DOMAIN = 'localhost'

    Finally now I could post to a newly created list with the newlist command (of course does not show up in ispconfigs lists!)
    so now I manually added the stanzas I made duplicating a newlist created block with ones for theeldestgeek (the list I had before, and which the data was all knows to mailman, but was inaccessible!)
    made the entries in aliases, and virtual-mailman - ran newaliases and postmap /etc/mailman/virtual-mailman, and voila! I can post to my old mailman list as I did before the mirgration!

    This may not be clean, but it does work. now maybe I can work out why ispconfig3 is not generating lists itself!

    hopefully this will help someone!
    cdb.
