I *promise* you that the problem you were experiencing has nothing at all to do with rcpthosts or morerecpthost. If you have no entries in virtualdomains and none of the domains in question is listed in locals and you're only acting as a secondary mail exchanger for these domains, then you have a DNS problem. qmail-smtpd accepted the mail and queued it, qmail-send determined that the mail was to be delivered remotely since the domain of the recipient wasn't in locals or virtualdomains, and then qmail-send found that it itself was the best-preference mail exchanger. These are the only conditions that produce this error. The DNS problem may have been transitory, or it may be that only one of the domain in question's authoritative name servers is giving out bogus information, but this definitely is or was a DNS problem.

You're just misunderstanding the problem. Ignore rcpthosts and morercpthosts for now; they have nothing to do with the problem. As Henning said, they're consulted only by qmail-smtpd (well, and qmail-qmtpd if patched appropriately). Somehow, a message got into your queue, destined for a user at domain foo. qmail looked in its locals file and virtualdomains file and didn't find foo. It therefore knows it has to deliver the message remotely, over the network. It therefore did DNS queries for the MX record(s) for foo, and if it found none, the A record(s) for foo. Imagine its confusion, then, when it found that the DNS system told it that foo was itself. Hence the error message you received.

rpcthost and morercpthost thresholds
I manage a backup mail spooling server (secondary MX) for around 6800 domains. Until recently, I've been putting all the domains in morercpthosts and then running qmail-newmrh to hash it in to the morercpthosts.cdb...logic being that parsing a cdb is more efficient that a 6800 line text file. This has been working great for the last several months. Last night, I began noticing that Qmail was ignoring (some) entries in morercpthosts.cdb and was returning the message about being listed as best MX preference but the domain not being local. Using strings, I confirmed that the domain having the error was in the cdb, as well as the plain text morercpthosts. Neither re-running qmail-newmrh, nor restarting qmail had any effect in correcting this. I eventually had to just drop all 6800+ domains into the rcpthost file. Things worked fine after that. Is there a limit to how much can be put into morercpthosts? Is it a limit of qmail-newmrh? Am I going to reach a limit to how many hosts I can put into rcpthosts as well? Any advice or assistance would be appreciated. -CT

Re: rpcthost and morercpthost thresholds
This server has NO virutal entries at all. There isn't even an /etc/qmail/control/virtualhosts file. It's sole purpose is to act as a backup mail server when the primary MX's for any of the 6800+ domains aren't working. Outside of the server's own hostname and localhost, there are no other entries in the /etc/qmail/control/local entries at all. The only qmail files that were ever modified on a regular basis before this problem were morercpthosts and morercpthosts.cdb. In my original email, I mentioned that I had restarted qmail (qmail-send) with no effect. The errors only stopped once I had migrated all the domains from morercpthosts/morercpthosts.cdb to rcpthosts (which took effect immediately with no need for restart). Even on the servers I maintain that DO have virtualhost entries, I've never had to HUP qmail-send to have the changes take effect unless vadddomain of vpopmail automatically sends a HUP. My original questions stand: Are there limits to the number of entries in morercpthosts/morercpthosts.cdb? I really don't have a problem with maintaining a completely flat-text rcpthosts, but a binary morercpthosts would be more efficient. According to the doco's I've read about rcpthosts and morercpthosts.cdb, morercpthosts.cdb is effectively appended to rcpthosts, but is read faster due to the hashing. In the case of my 6800+ domains, I would like to stick to the most efficient method, as this list is only getting bigger by the day. Do I need to HUP something after making changes to morercpthosts.cdb? I've never had to do that before. Changes always seemed to be immediate in the past. Any other insight would be greatly appreciated. -CT Chris Johnson writes: On Wed, May 16, 2001 at 11:24:44PM +, Christopher Tolley wrote: I wish it were that simple.
