David I have been off the list for a few days and missed this discussion. We have 3 E-Mail servers, 2 of which are backup MX's and 1 master, I wrote a small chkuser-style-server on the master server and a chkuser-style-client for both the MX's. This for us works perfectly and no files have to be migrated from the master to the backup's. The server is very simple (it does not actually use chkuser, but just chkuser style functionality), and the client communicates with this server to validate destination addresses. The client is called using a qmail-check-recipient patch (not sure where it came from, I might have even written it). It may be possible to write the server to use chkuser and have clients on the relay machines.

I now approaching to a solution that could be more easy than expected (and you suggestion could be another good one to add). But together with this feature I have a lot of other features to add, and I feel a lot within qmail must be rewritten in order to have those features working. I will evaluate a way to move to a really free Open Source qmail clone, more easy to update and be added of new features. If I will not see a feasible way, I'll continue with standard patching.

Re: [vchkpw] Chkuser - on relay server
John Simpson recently posted his patch that parallels conceptual functionality from CHKUSER but separates depedencies as I read it. Might be a fit, haven't tried it... http://qmail.jms1.net/patches/validrcptto.cdb.shtm Szeki - Inc wrote: I have a relay server, and have a backend with vpopmail, another with sendmail (old install), and some other (inlcuding winfs szerver too). I want to use chkuser to check the recipient from a combined list, or cdb, or sql storage, to allow only valid recipients to the backend servers. (so they can't use catch-all, or it can be configureble like [EMAIL PROTECTED]) I can make a big list, from all the users I have on the backends, and I want chkuser to check the recipient aginst this list. It is possible ? There is a program, witch can handle this(RECIPIENTS extension), but it is hard to integrate for me with qmail. (If someone can integrate it, or modify it to fit in shupp's toaster, so after patching qmail with it, I can patch this on top of it, than I will be more than happy :) Possible problems: alias extensins Peter

Only problem is you will have to maintain the user list in two places. (real server and relay server). Regards, Rick
