Welcome messages to mail list members are sent after migration

Symptoms

There are domains with mailboxes and mailing list(s) on a Plesk server that were migrated from another server. After the migration, all mail list members received welcome messages about being added to their mail list again. That is confusing for customers. How to disable that messages?

Cause

The wrong Mailman configuration was used during the migration. The issue will be fixed in a future release of our product.

Resolution

As a workaround, to disable the welcome notifications, set the value of send_welcome_msg in the Mailman configuration to zero on the destination server before the migration:

  1. Back up the original file:

    # cp /usr/lib/mailman/bin/add_members /usr/lib/mailman/bin/add_members_backup
  2. Then, replace the red line in the /usr/lib/mailman/bin/add_members file:

     166 listname = args[0].lower().strip()
    167 nfile = None
    168 dfile = None
    169 send_welcome_msg = None
    170 admin_notif = None

with

    send_welcome_msg = 0
  1. Restart Mailman:

    # /etc/init.d/mailman restart
  2. Start the migration.
