You can try sending a GTUBE through. So have we really narrowed it down at all? We know that spamd is taking a long time during some test it performs, but we don't really know if its related to RBL checks. Well, we've proven it's network related, but haven't narrowed it down to which network check. -D may help, I would probably try slowly reenabling things. ie: remove -L but disable razor, dcc, pyzor, URIBL, etc. Also, check to see if you have any timeouts set to 15s. The default RBL timeout is 15s, so it could be that, but most of the queries would have to fail to actually get to 15s (as queries return, the timeout gets lower). First off, I'd like to thank you again for your and others help, Theo. I would have been completely lost without your help and suggestions, and I really appreciate your patience. I finally got a chance to take a look at this with debugging enabled (been very busy here), and noticed the following output: Dec 8 10:08:13 dhgsrv17 spamd[1880]: debug: DNS: timeout for rfci_envfrom after 15 seconds Dec 8 10:08:13 dhgsrv17 spamd[1880]: debug: DNS: timeout for NO_DNS_FOR_FROM after 15 seconds Dec 8 10:08:13 dhgsrv17 spamd[1880]: debug: DNS: timeout for ahbl after 15 seconds Dec 8 10:08:13 dhgsrv17 spamd[1880]: debug: DNS: timeout for NO_DNS_FOR_FROM after 15 seconds Also worth noting: Dec 8 10:07:58 dhgsrv17 spamd[1880]: debug: URIDNSBL: domains to query: Dec 8 10:07:58 dhgsrv17 spamd[1880]: debug: is Net::DNS::Resolver available? yes Dec 8 10:07:58 dhgsrv17 spamd[1880]: debug: Net::DNS version: 0.45 Now, I believe the problem *may* be due to the fact that I'm relaying off this host by connecting from my workstation on the SMTP port, with no reverse DNS entry. Is it possible the resolver is timing trying to reverse my private IP address to a valid host name?
