That's excellent thanks. Are there any pitfalls potential loops etc I
should be aware of.
I guess if company x sets up a catch all account it will prevent the double
bounce. Is there any danger of that double
bounce becoming a loop, or possibly leading to our server being listed as a
spam source?
Anythings possible. You will be notified of double bounces, otherwise
you will just do a regular bounce to users.
Last question, is it really that easy? :-) If so that is excellent news,
and news that I'm sure will earn me some good points
with the boss. Thanks for that.
Yes, it really is that easy.
As for the Wiki, I will indeed add the info, is there anything else I should
include, or is the basic premise, change Mx to point to scanning server, add
smtproute to receiving server and add domain to rcpthosts?
Ensure that you follow the format of domain:remoteserver:port from
/var/qmail/doc/README.remote-auth
For example: gmail.com:mail.gmail.com:25
Otherwise this will not work. I just mention it, since the default
smtproutes doesn't need port.
Will qmail accept the mail even though users don't exist? If you add the
smtp route for domainx, does qmail just interpret that as "forward all mail
for domainx to this address and don't check locally?"
No, re-read my original e-mail. You must add it to rcpthosts (tells
Qmail to accept for that domain) then add an a line in smtproutes for
Qmail to figure out where the destination truly lies.
Thanks again for the replies, this list is the best.
Regards
Craig

The answer is yes. You can scan other domains frm your box.
The mx points to you. You put an smtproute that points to their server
and you add the domain to rcpthosts.
The problem is going to be double bounces. Since your box doesn't have
a list of valid users, it will accept any mail addressed to
companyx..com. If a [EMAIL PROTECTED] doesn't exist, your box will get
a rejection which it will try to send to the sender. Since this is
usually spam, the sender address probably won't exist and you will be
notified of the transaction.
