Some additional informations:
This is the original dataset from vmail.alias
# address, goto, name, moderators, accesspolicy, domain, islist, is_alias, alias_to, created, modified, expired, active
'2016@xxxxxxx.com', '2016@xxxxxxx.com', '', '', '', 'xxxxxxx.com', '0', '0', '', '2016-06-17 08:26:39', '0000-00-00 00:00:00', '9999-12-31 00:00:00', '1'
"address" and "goto" are the same. May this be caused by "old" data from previous iRedMail installations?
I do not understand the purpose of this dataset.
I wonder if the migration script can be improved by *not* migrating these kind of "aliases" as they are useless.
Have other users experienced the same issues?
