Windows Server Forum / Exchange Server / Transport / March 2008"The connection was dropped by the remote host" Issue
Hi everyone. I hope someone can help. I have read through previous posts and i am having a problem with E2K and about 4 or 5 domains where messages are not being sent due to the connection being dropped. I turned on the logging for the SMTP server, and I discover that E2K is connecting to other mail server, exchanging information and the disconnection seems to occur duirng the DATA phase. I do not recieve any message waiting to be qued repsonse in the log file. I tried using Netmon to capture and filter information but i have not used it many times before and i could not understand what i was looking for. If anyone can wither help me with my problem, help diagnose it using NetMon or help find a way to bypass the problem for the couple of domains i would be very grateful! Matthew Sutton Hi Matthew, Can you let me know the 3 or 4 domain names you are having trouble with? I would like to do some quick testing here to see what they all have in common that could be causing the problems. What happens when you use telnet and manually drop a message on the server. 153119 XFOR: Telnet to Port 25 to Test SMTP Communication http://support.microsoft.com/?id=153119 Jeff Thibodeau Microsoft -- Get Secure! - www.microsoft.com/security -- When responding to posts, please "Reply to Group" via your newsreader so that others may learn and benefit from your issue. -- This posting is provided "AS IS" with no warranties, and confers no rights. ========================================================== -------------------- From: "Matthew Sutton" <msutton@here.we.go> Subject: "The connection was dropped by the remote host" Issue Date: Wed, 19 May 2004 16:09:41 +1000 Hi everyone.

I have configured all connectors get incoming mail ok but outgoing just queues up with the message "The connection was dropped by the remote host" This happens on many different destination domains.... I have tried both "use dns" to send and also "use smart host" but get the same result. I can telnet to most of them manually so its not a blocked connection or anything. I'm starting to pull my hair out so hope someone has a fix for this issue soon!

It;s Urgent Thanks -- tsichles ------------------------------------------------------------------------ View this thread: http://www.webservertalk.com/message230860.html Are you running Symantec AV 9 Corp on the mail server? I had the same issue as you're describing. I tracked it down to Symantec A/V installed. By default it had installed with Email autoprotect enabled. Turning this off and restarting the smtp virtual server, emptied the queues out to their respective destinations in seconds. No problems since. Hope this helps you. Cheers, Brad This is correct - but to be more specific - it is the NAV Client - not Symantec Mail Security that is the problem - Here is the Symantec Knowledge base article describing the problem: Document ID:2004061009504348 Last Modified:09/08/2005 Error: "Your email message was unable to be sent because your mail server rejected the message." (1003,11) or (1003,12) You will not see these things occur unless you Unistall Symantec Mail Security. The problem is the NAV Client - It causes the e-mail problems. Turns out the NAV Client has a Proxy built in- that must be unistalled on mail servers > Are you running Symantec AV 9 Corp on the mail server? > I had the same issue as you're describing. I tracked it down to [quoted text clipped - 10 lines] > > Brad Folks, I have been trying to find a solution to a problem which sounds very similar to the one in this thread. SBSR2 server, Trendmicro CSM, Netgear DG834 router - basically any email with attachments over about 500K gets stuck in the SMTP queue with a "connection dropped by remote host". Have run smtpdiag and manual telnet connections which all work fine. Exchange folders are not scanned by Trendmicro and I have reduced the "not to be scanned" setting down to lowest setting. The netgear settings, short of a newer firmware version, are the same as numerous other installations I have done - though I did find another forum which basically echoed this problem which was resolved by some setting on the router - to this point in time I haven't found out what this setting was. have change MTU from 1500 back to 1492... I would really appreciate any other suggestions to resolve this one thanks in advance  Signaturespallw Hi Matthew Did you ever sort this out? I had the same problem which turned out to be the router it was a Netgear DG834GT. Changed this for a TI one and the problem was solved. The red herring with this problem was when the server was restarted mail started flowing for a short while! > Hi everyone. I hope someone can help. > [quoted text clipped - 15 lines] > > Matthew Sutton Try adding the IP address of the web server in the Relay Restrictions of its SMTP server. In other words, Say the IIS Server that sends the e-mail has an IP address of 192.168.168.25. 1. Go to the IIS Admin MMC ~ the SMTP Server properties ~ Access ~ Relay 2. Choose "Only the list below" and add 19.168.168.25 to the list 3. Leave bottom checkbox checked that talks about authenticated users 4. Hit OK and mail should immediately be delivered Hope this helps, this just worked for me and I have been battling the same scenario you described for the past 6 days. > Hi everyone.
