"Disconnection before command received" ???

[winter]

I have one user that is having trouble connecting to the mail server. It does not matter if they are using POP3 or connecting through the HTTP web mail. From their point of view it appears that the mail system just hangs. It looks like they are able to connect for a few seconds, then it locks them up before it can download any mail, or send any. It is only affecting this one user and it is driving me nuts trying to figure it out!

I don't know if the error codes should be telling me something or not...Has anyone run into something like this and found a solution? Here is what the POP log shows...

Thanks in advance for any thoughts or suggestions you can offer!

This is a client side issue the error 10054 is saying that the client is disconnecting, but I am sure you have worked this out.

To confirm this completely I would suggest you try and connect to the mailbox using a different PC/client and check to see if there are any issues still.

On the client side of things look for possible software that is blocking the connection forcing timeouts, the most common issue is AV or firewall software on the client. Disable any proxy, AV or firewall software on the client an test again.

If this software side of things does not help then check the hardware are any other connection based software programs being affected. ie explorer, ftp

Ben, thank you for responding.

I figured it was a client side issue, but the weird thing is, it appears to only be my web server that she cannot connect to. I have disabled all AV and firewall software on her PC, and she can reach every web page (except my web enabled email server) and she can FTP every site I try, and she can even ping my IP #. It is just when I try to connect to the mail server it bombs out. Since it is only connecting to her email (no matter what method she tries) I thought it might have something to do with the MailEnable software.

I host about 50 people's mailboxes, and this is the only one having any trouble...the problem is, she happens to also be my Mom so she seems to think she has the right to complain loudly!!!

Oh well I will keep digging. Thanks again.

No problems, may be worth trying to telnet to the server from the client and seeing if this works. It may give you more information on exactly when the client is disconnecting.

Here is some information on the telnet service;

Not sure if anyone found a solution to this or not...my guess is that there are multiple clientside issues that could cause it. For me after some digging in the logs it was easy to find. I kept getting the same 10054 error but only from one client. This client was using Outlook 2003 and had Outlook to check for new email every 1 minute. The problem was that he was checking 5 different email accounts with this same Outlook 2003 install. Which means it was actually taking longer then one minute to check all five accounts before Outlook was trying to check for email again.

I also noticed that his ISP changed his IP address randomly throughout the day. He would get this error whenever the ISP would change his IP address. AND when he was checking his email at the same time. Which of course was constant.

I had the client change his Outlook settings to check every 5 minutes and the problem appears to be solved.

hi there.
i have a similar issue also.
