Okay so far, except that the concept of discarding mail is generally not a good idea. Why do you want to do that? What would be wrong with rejecting that address? That said, as P@rick points out, we do have a discard(8) delivery agent which can be directed to using transport(5) maps. http://www.postfix.org/transport.5.html http://www.postfix.org/discard.8.html http://www.postfix.org/postconf.5.html#transport_maps > - Added the following in mysql_virtual_alias_maps.cf: > no-reply@<my domaind> = blackhole This sounds wrong. Furthermore, it is not a good idea to use a bare username in place of a full email address. You should have used "blackh...@some.domain.listed.in.mydestination". See virtual(5) for the format of virtual_alias_maps lookup keys and results. See mysql_table(5) for the details of setting up a query in Postfix. See MySQL documentation for information about setting up a database in mysql. http://www.postfix.org/virtual.5.html http://www.postfix.org/mysql_table.5.html http://www.mysql.com/ > - Ran: > postmap /usr/local/etc/postfix/mysql_virtual_alias_maps.cf (it's You do not compile a query file with postmap.
