Michael, =20 Test your DNS from that box using nslookup. From those symptoms, it = sounds like DNS queries are taking a long time to complete. =20 =20 - Bob Coffman -----Original Message----- From: ass...@li... [mailto:ass...@li...] On Behalf Of Micheal Espinola Jr Sent: Tuesday, October 31, 2006 2:48 PM To: Questions and Answers for users of ASSP Anti-Spam SMTP Proxy Subject: [Assp-user] Ever have a performance problem with RBL and SPF ? Hi everyone, I recently performed my first installation of ASSP that was not with Microsoft Exchange and not within a self-controlled DNS environment. = This time, the MTA is MailEnable and the server and DNS are at a hosted co-location facility. My problem so far, as indicated with the subject line, happens when I = enable RBL or SPF - individually or together. Web interface performance slows = to a crawl, taking 5+ minutes for a page refresh. The outbound mail queues = also get clogged during this performance hit. Incoming connections time-out. = It appears as if ASSP is severely lagging on something. If RBL and SPF are off, ASSP performs just as I know it should - wonderfully. I'm a bit befuddled at the moment... Here's the info about the box: Processor : (2) P4 4 GHz Memory : 1 GB (~330 MB free) Windows : 2003 (SP1) Perl : 5.008008 ASSP : 1.2.5(2) Compress::Zlib : 1.42 =20 Digest::MD5 : 2.36 =20 Email::Valid : 0.176 =20 File::ReadBackwards : 1.04 =20 Mail::SPF::Query : 1.999001 =20 Mail::SRS : 0.30 =20 Net::DNS : 0.59 =20 Net::LDAP : 0.33 =20 Time::HiRes : 1.86 =20 Win32::Daemon : 20030617=20 I have never dealt with a similar issue in my experiences with ASSP - so what I'm wondering is if anyone has encountered an issue similar to this = (I didn't come across anything similar in the archives), and if anyone with experience (nudge Fritz, et all ))) ) has an recommendations for me in = order to troubleshooting issue this effectively. Thanks! |
