You didn't tell us what method you are using to run qpsmtpd (e.g. tcpserver, forkserver, Apache, pre-fork, aldus lamp). If the client is timing out before you can send a banner, I wonder if your server is thrashing itself to death. You can't just up the limits willy-nilly, and expect everything to continue working. If you were running the trunk code, which is the former high-performance branch, it might be a different story. The other thing to check is, if you are using tcpserver, you aren't trying to resolve the IP address of the boxes that are connecting. If you have a poorly configured DNS (like M$loth's), it might take forever to time out. You should always call tcpserver in this instance like: tcpserver -H -l localhost ... which won't do any lookups... HTH John
