RE: [IMail Forum] SMTP TIME-OUT HELP!

Well, I never took the time or resources to find out the why, but I have confirmed (via viewing the packets in NetMon) that on a Windows Server 2003 with MS DNS running and Imail Anti-Spam DNS based tests running, the request for information packets are sent from the server, the server receives the acknowledgement with correct data, but that data is never processed by Imail. Instead, 30 seconds later is makes a new request, and again never process the returned data. At 1 minute after the first request, Imail logs and error on that test and goes to the next test. This means that if you have 10 DNS based tests running in Imail Anti-Spam, you are experiencing a 10 minute delay in each message with the logs showing a DNS error.   John Tolmachoff Engineer/Consultant/Owner eServices For You   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sergio Rinc�n J Sent: Thursday, April 29, 2004 8:06 AM To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] SMTP TIME-OUT HELP!   Yes, i have Win2003 + MS DNS and Imail point to 2 DNS from my network. The other one (DNS SERVER) is at a Win 2000 server.   Please confirm me the win2003 issue that you know, but also, i had the same problem (With the same config) with a win2000 server (Same box, plus same software Imail + Windows 2000 + MS DNS  + DECLUDE + FPROT 32 Bits)   Today I upgraded to Imail 8.1 HF2 to see if it changes something!   Thanks for your Time! ----- Original Message ----- From: John Tolmachoff (Lists) To: [EMAIL PROTECTED] Sent: Thursday, April 29, 2004 9:53 AM Subject: RE: [IMail Forum] SMTP TIME-OUT HELP!   Start by answering the question. Are you running the MS DNS service on the Windows Server 2003 box and is Imail using that as its DNS server?   John Tolmachoff Engineer/Consultant/Owner eServices For You   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sergio Rinc�n J Sent: Thursday, April 29, 2004 6:31 AM To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] SMTP TIME-OUT HELP!   Hi john.   Thanks for your help, but still cant find the messages you say.

If so, check the archives, known problem when using Imail Anti-Spam and MS DNS Service on a Windows 2003 server.   John Tolmachoff Engineer/Consultant/Owner eServices For You   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sergio Rinc�n J Sent: Wednesday, April 28, 2004 3:21 PM To: [EMAIL PROTECTED] Subject: [IMail Forum] SMTP TIME-OUT HELP!   Hi there:   We are a medium size ISP , Imail server V 8.05     From days ago, we are experiencing some sort of strange problem.   We have an IBM Dual Processor 2.8 Ghz Xeon 2.5 GB RAM Level 3 RAID 70 GB HD's   Windows 2003 (Was Windows 2000 but same problems) + Imail + Declude AV + F-prot (32 Bit)   This system is purely for our Imail and about 200 Vhost's and 1 Primary Host for imail woth more than 13000 Users.     Email is getting stuck in the queue, if you follow up the Logs for the emails, the last call for the process is "Performing anti-spam checks' and if you go to the spam logs(Imail's AntiSpam Feature), the process says that the email is spam-free, but there is no rdeliver process created for the File in the queue.   So we had to install an alternate POSTFIX server, purely for delivering the Imails Emails, by checking at the imail server, the "Send all remote mail through gateway" option and pointing to the POSTFIX machine. This worked fine when we were not using ANTI-SPAM features of Imail, (But still have the queue stuck problem if we unchecked the send all email through gateway, oonly thing is that in the logs, the email never got an rdelivery process).   If you check the ALERT MANAGER via WEB (8181 port) sometimes it says that SMTP is DOWN (TIMEOUT 60 SECS).     May it be a Hardware-NIC Related Problem????   Even if debugging is turned ON at SMTP LOGS, the log files show the same for the Email, gets stucked after SPAM CHECKS.   Thanks for your help!   Sergio Rinc�n Jaramillo    Ingeniero Telem�tica GeoNet S.A.    TEL (574) 5104701 Fax (574) 2350160 L�nea �nica de Atenci�n al Cliente 3500111 Calle 34B N� 66� 42, Medell�n, Colombia   Ya visit� nuestro sitio www.geo.net.co   Las opiniones que se expresan en este e-mail son personales y no necesariamente coinciden con las de GeoNet S.A.
