Description Nico Stöckigt

There should be a possibility to setup a Catch-All Address to receive all eMail there is no mailbox for.
Postfix allows this by adding a '@maildomain'-Entry to the virtual.db.

In UCS there is [postconf]

virtual_mailbox_maps = ldap:/etc/postfix/ldap.virtual_mailbox, ldap:/etc/postfix/ldap.sharedfolderlocal

that's why I assume there is no way to do this. UMC returns 'invalid Mail-Address' when trying to enter just '@maildomain'.

It's also a very bad idea to create a catch-all address.
It leads to the system accepting all spam emails and then sending bounces instead of rejecting it in the SMTP dialogue.

It is usually a sign of bad system design, as all senders should know their targets.

What is the scenario for such a feature?
