This feature is not advertised in the Postfix documentation,
therefore it is not available. On the contrary, a point of virtual
domains vs. local is this namespace separation.
Generally a solution is to list postmas...@example.com and
ab...@example.com in virtual_alias_maps pointing to your (the
postmaster's) address.
Lazy solutions are available to users of SQL map types:
main.cf :
[ ... ]
virtual_alias_maps = [ ... ]
sqlite:/etc/postfix/query/map-postmaster.query
virtual_mailbox_domains =
sqlite:/etc/postfix/query/dom-vmbox.query
[ ... ]
query/dom-vmbox.query :
dbpath = /path/to/your/database
query = SELECT name FROM Domain WHERE CLASS>800 AND name='%s'
query/map-postmaster.query :
dbpath = /path/to/your/database
query = SELECT name FROM Domain WHERE CLASS>800 AND name='%d'
AND ('abuse'='%u' OR 'postmaster'='%u')
result_format = you+%u...@example.com
So if
postmap -q example.net sqlite:/etc/postfix/query/dom-vmbox.query
returns "example.net", then:
postmap -q ab...@example.net sqlite:/etc/postfix/query/map-postmaster.query
will return "you+abuse_example....@example.com".
The gist of this being that you do the same test as for your virtual
domain list, test two hardcoded localparts, and return a hardcoded
result which goes to your mailbox.
Note: I don't use this; I manually create postmaster and abuse
aliases. It's untested. Test it before you commit. :)
