You do. In regexp/pcre you can enclose the LHS (local-part) matches in an IF/ENDIF loop with the domains: if /\@(example\.com|(other|third)\.example)$/ ... your LHS stuff ... endif (Escaping of the \@ is necessary in PCRE but not POSIX RE.) With domain lists in SQL, this is trivial -- I have posted this solution before, recently. Simply do the magic in a SQL query with hardcoded values for the LHS matches. I do have my domain lists in SQLite, but I don't do this. I just add postmaster/abuse aliases when adding a domain. If this is something commonplace, you can script it. It looks like you are duplicating alias_maps in virtual_alias_maps. You probably don't need all those aliases for each virtual domain. I think the purpose of all the default aliases(5) in alias_maps was originally to prevent Internet mail from being delivered to system and daemon accounts. These accounts must exist in the local passwd(5) database, but you don't want them getting mail. Also note that alias_maps does this perfectly for $mydestination local(8) domains. The RHS (domain-part) is ignored. -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
