If you get either 1 or 2 instances of each message (not more than 2) then the cause definitely is a DNS timeout (probably checking RBL/DNSBL). The result (DNS failure) is cached, so the second time the message is accepted much faster, so the sender doesn't repeat anymore. >It does seem like we are going to need to beef up the Exim hardware and >perhaps go to local RBL. I'm talking of timeouts while querying external servers, if my guess is right then upgrade of your hardware will not help. >>I guess that your spam-filter queries some RBL, and one or more of them >>timeout because dead or for paying customers only. >>Try switch spam-filtering via spamd off temporarily. >>If that doesn't help then try to switch virus-filtering off temporarily. -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
