The key may be your OS. Windows XP Pro is a workstation, not a server. There are inherent limitations that come with that. One of those limitations is the number of concurrent connections allowed.

Fullerton, CA 92835 www.reliancesoft.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Timm Jasper Sent: Friday, May 31, 2002 8:06 PM To: IMail_Forum Subject: [IMail Forum] SMTP Problems Greetings Gurus of all shapes and sizes, First I would like to say I usually find the answers to my mail problems before they become problems by reading this forum. Perhaps someone can solve my dilemma. I have reviewed the KB's and have found no answers looking over the message archives, I have also hacked the registry following instructions in the kb's for allowing more sockets, assigning more memory, etc... Here is the system, I have v7.07hf2 running on a tyan dual athlon board with 2 1800mp's, the board has 2 3com ethernets built in along with an ATI based video controller, 512mb registered ddr ram and XP pro (all basic ms startup services have been turned off except for workstation, restore, and a couple of other necessary services - I even turned off themes). The drive system is 4 40gig 7200's running mirrored and striped on a Promise raid controller. The boot drive is a 40gig 7200 and runs off the mainboard. The spool is on the raid the swap is on the main. The system had Diskkeeper running in 'Continuous' mode (that is now off, thought it might be causing problems locking files) We currently have Declude PRO for AV and Spam (thanks Scott), and we use F-Prot 3.12a as our av scanner. Everything is fast. But smtp will just stop accepting connections (10061 error on Outlook Express) for no apparent reason. There are NO corresponding errors in the log files. I have 2 machines running postfix as my gateway servers, these are the mx entries for the domains, the Imail server has no entry as a mx server (Thanks, Len) even those will have a 'Connection denied' sending to the mailbox server. During the time it wont accept a smtp connection it will accept a pop3 connect, and it pops up on a terminal screen as quick as you hit the return key. Even when it is accepting connections smtp may take upwards of 10 seconds to respond when telnetting into port 25. I'm at a loss, the machine never exceeds 260 megs of ram usage, it never goes over 10% network usage and there is currently 45 gigs of drive space le ft. When it first started happening, I thought it was my desktop machine (too much stuff running at the same time) I would have to click send and receive two or three times to clear the outbox. Then my customers started complaining, so I started looking deeper. Is it XP? Is it the built in ethernet? Is it Imail? Is it something else? I no longer have the will to read, and I need a sandwich. Thank you in advance. -- Timm Jasper -- Systems Administrator -- TQCI -- Phone: 301-863-6121 -- Fax: 301-863-7544 --- [This E-mail was scanned for viruses at tqci.net] Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
