The trick is that postmap is "dumb" - it doesn't know *why* you're searching, so it doesn't strip the local part. This confuses people sometimes because using `postmap -q` isn't the same as what Postfix does, Postfix does a lot more. The lookup mechanism is entirely generic, it's just key->value mappings. It doesn't know what an email address is, or what it looks like. The apparent deficiency here isn't a matter of by-design or not-by-design, it's just not a consideration. As you've probably guessed by now, if you think like Postfix, you'll get what you expect. glorang:~# postmap -q @mydomain.be /etc/postfix/generic accep...@relayhost.other.domain
