Now wheneve someone tries to relay mail through your postfix mailserver it would assume that the mail is meant for a user on the localdomain(and abc.net in this case is your localdomain as far as postfix knows). And as far as your DNS goes, for that too, localdomain would have priority for being abc.net rather than it going and looking for the actual abc.net.

You can set up rules or aliases that [EMAIL PROTECTED] should go to [EMAIL PROTECTED] and that will be delivered locally. If an email shows up as [EMAIL PROTECTED] and there is no alias for that, it will be SMTPed out to the abc.net MX. - Ankur.

Use a different domain for your internal use (like abc.off), configure fetchmail to rewrite the envelope recipient before sending mail to the local postfix server (fetchmail global parameters smtpaddress, AFAIK). Configure postfix to make this domain as the local domain. Downside is that mails sent to even local users using the original domain will be sent out to the Internet and downloaded again.

Look at: http://www.postfix.org/rewrite.html#luser_relay Interesting. fallback_transport seems to be the way to go. :) I should be reading up the postfix hacks more often. Quite a postfix specific solution though. Solves the OP's problem in any case. Umm...more of PostFix feature. That's why I choose particular MTAs in particular cases - depeding on the feature set they provide. Varun, while you could address the OP's problem with this Postfix hack what do you do when you are not using Postfix as in this case? Take up the absolute wrong way? ;) Nope. Generic solution for all MTAs: Create aliases/rewrite rules for offsite addresses. E.g., for sendmail, in /etc/aliases: offsiteuser: [EMAIL PROTECTED] E.g. Domain is: abc.net, create a hostname like mail.abc.net, which points to the IP[s] of the MX. The downside of this this is that the backup MXs would not be used in case the primary is down, but there are two solutions for that: - Set up the DNS to return IPs for mail.abc.net same as the MXs in round robin. - Setup the mail.abc.net as a CNAME pointing to abc.net. That way the MX resolution for mail.abc.net would be the same as for abc.net. Never tried it and it *might* fail on some MTAs, which start looking at the DNS query reply in detail instead of accepting the returned IPs. This approach would have the side effect to changing the envolope address to mail.abc.net for mails to offsite users that come from a particular site. Depending on how you see it, that's a feature/bug. With Exim you can do this by setting up routers/directors/transports accordingly. Anyone know how to do this in sendmail, without using aliases? I hate qmail, and never looked at Courier. And, yes, I don't know how to do this with M$ Exchange. Also, if you really need to create a local domain, I highly recommend creating it as a legitimate subdomain, e.g. delhi.abc.net - lets you use dynamic DNS, and in my opinion, looks better. -- Regards, Varun Varma --- Mindframe Software Services Pvt.

If you are telling postfix that it is the authorative mail server for the domain(by setting localdomains), why will postfix even consult DNS or try to forward mails elsewhere for the same domain? Mail routing decisions are based on domains, not users. There is no standard way of configuring any mail server such that half of their users lie on one server and half on some other server. The solution as I suggested, is to configure a different local domain for your private LAN. - Sandip -- Sandip Bhattacharya sandip (at) puroga.com Puroga Technologies Pvt. Ltd.
