Mail is being forwarded, but no forwarding settings are shown in the control panel interface.
For example, here is a redirect from
[root@mail ~]# cat /var/qmail/mailnames/domain.tld/mail/.qmail | true &firstname.lastname@example.org
The database was not properly updated during the upgrade. All redirect (forwarding) records should be moved from the psa.mail table to psa.mail_redir.
If you need an urgent solution, do the following:
Make a backup of the psa database:
# mysqldump -u admin -p`cat /etc/psa/.psa.shadow` psa > ~/psa.`date +%F_%H:%M`.sql
Update the psa database manually:
mysql>insert into mail_redir (mn_id, address) select id, redir_addr from mail where redir_addr <> ''; mysql>update mail set redir_addr = '', mail_group = redirect, redirect = 'false' where redir_addr <> '';
