"The connection was dropped by the remote host" Issue

Matthew Sutton · Joined: 06 Aug 2007 Posts: 2

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!

Domain 1 - hotmail.com
Domain 2 - unilever.com
Domain 3 - rsmi.co.za

There are others but i wont list them.

I have manually tried telneting into these servers and running the test
mentioned below. It all seems to work fine.

Here is the response i get back:

220 relay21.unilever.com (IntraStore TurboSendmail) ESMTP Service ready
250-Requested mail action okay, completed
250-8BITMIME
250 SIZE 3072000
501 Syntax error in parameters or arguments
250 sender OK
250 recipient OK
354 Enter mail, end with "." on a line by itself
250 Message received and queued

When i try and send to the same recipient via E2K this is the resulting log
file

I have the same error. I tried the SmtpDiag tool and it reported everything
ok (all Green). Anyone have any luck fixing this?

Thanks

Hi MAtthew,

Did you resolve this. I have the issue on Exchange Server 2003 ...

smtpdiag says all is OK, but mail to some domains dies during the DATA
phase. OK by telnet.

Any suggestions?

- Neil

I too have a similar issue with a newly installed SBS 2003.
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!
Thanks

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

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!

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.

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
