When I started our mail server I added aliasses to our database via the MySQL command line, all working well.

Example command:

INSERT INTO forwardings (address, forwarding, domain, dest_domain, is_alias, active) VALUES ('dennis@domain2.eu', 'dennis@domain1.nl', 'domain2.eu', 'domain1.eu', 1, 1);

Forward / Alias tested and working well.

When I go to the iReadAdmin-Pro dashboard, to the mailbox and the aliasses tab, I can see 'dennis@domain2.eu' in the list of 'Email addresses of alias accounts'.

However, I didn't pay attention to the remarks on the right of the list:

Emails sent to alias accounts will be delivered to user dennis@domain1.eu.
Email address of alias account must end with domain name(s): domain1.eu.

I added an alias to the existing list and pressed 'Save changes' after that he discarded al the aliases I've made for other domains. Only the aliasses of 'domain1.eu' we mentioned in the list and the others were gone.

I've readded those again via the MySQL command line and they are back in the list.

My question: why am I only able to add aliases for the same domain in that list via the GUI? And why am I able to add aliasses from others domaines via the command line?
