You won't see the 10054 error for not being able to
connect. this error means the connection was dropped by the other
end.

and send error 10054
Yes
I may try a different NIC. I have an integrated 3com NIC on a Dell Optiplex
GX240. But the thing that points me away from the nic is that I cant even ping
the IP in question - right after the error occurs, or even later, so the
server is not there, its not just a problem communicating. I ping the
addresses in question from my workstation and not the server, so its not just
the mail servers nic that cant communicate to the IP in question. It just
seems to me that its the behavior of SMTP when its trying to connect to a
server that's not there. Another thing is that I have never seen the
10054's at all if its a legitimate server. I have also done searches
through the log to see if any of the 10054 IP's ever do get a good connection,
and they don't. Another thing - Trace routes on the IPs in
question often show a net block from Japan, France, brazil, etc. This is
another thing that leads me to believe that there isn't anything wrong with
the nic. Maybe someone can answer this question - If, under normal conditions,
an Imail server tries to connect to a server that's not there, what is it
supposed to do, what should I see in the logs?
Thanks again for the response
Mike,
You may want to check your patch cable(s), the
port(s) on your hub/switch/patch panel/router etc.. Also, it
could possibly be a flaky nic. You may want to try a
new card. Imail seems to like 3com 905's. FYI, quite a few people on this
list seem to have had problems with "server" class 3com nics on Imail
boxes.
Hope this helps!

Timeouts and send error 10054
Thanks for the reply Jamie,
I saw that KB article, but this is an NT4 box,
and there are no power or standby options. Is there anyone who had a
similar problem and found a resolution with NT?
|
Answer/Solution: Go to the NIC
properties and hit the Configure button. Then click the Power
Management button. Make sure that both, Allow this device to bring
the computer out of standby, and, Allow the computer to turn off
this device to save power, are NOT checked. |

I am
having a problem with my SMTP service going down and back up again
several times per day. Thankfully it only goes down for a few seconds
and then goes back up just fine, but sometimes it will go down for a
few minutes. This occurs when I get the following entry in my SMTP
log. We are an ISP that's been around a while, and we receive approx
30,000 messages/smtp connections per day. I realize that most of those
connections are from spammers with hosed up machines and DNS
properties, but my log is riddled with entries similar to this one:
(IP and port have been replaced with x's because they are
random).
02-19-2003 20:37:00 SMTPD (0D6802C0)
[0.0.0.0] connect xxx.xxx.xxx.xxx
port xxxx
02-19-2003 20:37:00 SMTPD
(0D6802C0) send error 10054
This error
will show several different IP addresses so there's no real pattern to
it. Some have shown up more that others and I have entered several
IP's that have caused this error in the SMTP blocked IP list, but
there are too many of them to truly keep up on it. I know that this
error is due to a connection initiated by a spammer or some other type
of mail server that just doesn't work. Reverse lookups on the IP in
question rarely come up with anything, and usually the IP's in
question cant even be pinged. I don't really care that my logs are
filled with errors like this, but the problem is that whenever my SMTP
service goes down and back up for a few seconds, it is directly
related to the time that the send error 10054
occurred.
Is anyone
else having this problem, and is there anything I cant do to keep the
SMTP service from going down when this happens? This seems
to be occurring more and more, and I am getting more and more calls
from customers that think the mail server is down because they get a
POP3 error whenever they try to log in.
Thanks in
advance for any help with this one.
