Good Morning, I'm using Endian's SMTP proxy feature. It works extremely well in stopping spam and is remarkably accurate. However, for the last two weeks on Friday nights at about 8:00 - 10:00 PM PDT, it begins to lose the ability to perform RBL lookups, and starts rejecting all mail, leaving the following messages in the log. A reboot clears up the problem, but I've been unsuccessful in tracking down the root cause. Any suggestions?
Thanks! -Jeff Khoury Jun 15 23:06:22 firewall postfix/smtpd[31257]: warning: 186.64.100.85.sbl-xbl.spamhaus.org: RBL lookup error: Host or domain name not found.
