Use virtual_alias_maps instead of alias_maps. virtual aliases are
resolved for _all_ mail. so
foo
yahoo.com tnelson
starpoint.com
will forward mail destined for foo
yahoo.com to your account. even if
yahoo.com isn't a domain of yours.
PS. I get this from your system:
<tnelson
starpoint.com>: host mail.starpoint.com[207.239.34.137] said: 554
Service unavailable; Client host [82.239.111.75] blocked using
dul.dnsbl.sorbs.net; Dynamic IP Addresses See:
http://www.sorbs.net/lookup.shtml?82.239.111.75 (in reply to RCPT TO
command)
As a result, this is my last message to you. and as I don't want to restart a discussion with Matthieu Sullivan (we disagree, and that's it), I won't give any recommendation here.
