Feature request: Other ways to handle aliases

I am trying to migrate from Devecot/postfix to Stalwart.
I have my accounts and aliases on LDAP. There, I have my own objects for aliases, which aren’t just an attribute of the account:

dn: uid=f,cn=mydomain.eu,cn=postfixadmin,cn=mailserver,cn=etc,dc=ipa,dc=mydomain
uid: f
postfixMailAddress: [email protected]
status: TRUE
objectClass: postfixAlias
objectClass: top
postfixMailAlias: [email protected]

Is there a way this works on Stalwart? Would it connect that the postfixMailAddress is the mailbox for the postfixMailAlias?

it already is. This already works.
