in ISPConfig 220.127.116.11 I cannot change some of my (already existing) "email-forwarding-rules".
I've created a email-mailbox for a domain ("email@example.com"). Then I created (among other alias, forwarding rules and pop3-mailboxes) a catchall for this domain - redirecting to that (first) email-mailbox ("@domain.de -> firstname.lastname@example.org
"). The reason is that I only can select existing mailboxes as destination for a catchall.
Now I had set (in some release before... 3.0.1...) a forwarding for this mailbox to an external mail-address ("email@example.com -> firstname.lastname@example.org
If I go to the forwarding-page to change this setting now (or add a new one) I got the error message "Es existiert bereits eine Mailbox mit dieser Email Adresse" (already a mailbox with this address exists). Sure, that's right :-) but why it's a fault by now?
What other way exists to have following settings:
info@domain is mailbox (IMAP)
test@domain forwarded to info@domain
@domain forwarded to spam@external-address
