User/Domain prefix, qmail header rewriting

[kingfisher]

hello @ll,

is there a way to get rid of the header-rewriting plesk/qmail does?

So I'd like to have joe@domain instead of 76-joe@domain as recipient or my local mailserver will not parse the addresses correctly.

or is there a workaround for single mailboxes configuring them outside plesk?

thanks in advance
