Has been a while since I've looked at this, but at present if we
need to alias a domain, eg f...@example.com to f...@example.net
we are using mysql:/etc/postfix/mysql_alias_domains.cf after
other entries in our virtual_alias_maps
and using
query = SELECT email from virtual_users where email='%s' OR email =
CONCAT('%u@', (SELECT destination from aliased_domains where
domain = '%d'))
Consider adding a regexp or PCRE map for this:
virtual_alias_maps = mysql:/etc/postfix/mysql_alias_domains.cf
regexp:/etc/postfix/domain_aliases
/etc/postfix/domain_aliases:
/^([^@]+)@from_domain$/ $(1)@to_domain
It'll be faster than mysql, too ;)
No, don't do this.
I agree that he probably shouldn't do this in the first place without a
valid recipient map, but I was only correcting the mysql fiasco...
This breaks recipient validation in the same way that
@from_domain @to_domain
in an indexed map does, except it's more complicated.
Well, no, not "breaks" - just always passes it.
If you know why you're doing it, and will absolutely never send
backscatter because of it, it's possible to do so.
