Here is my issue.

When in the 'Inbox' or any other folder and when somebody has selected a
message or messages to delete or be moved to another folder.

When the delete or move button is pressed, it waits about 5 seconds and I
get this error in my web browser (specific to this message, Netscape 4.75.
IE gives a much abbreviated message);

>Problem Report
>             There was a communication problem.
> Message ID
>             TCP_ERROR
> Problem Description
>             The system was unable to communicate with the server.
> Possible Problem Cause
>             The Web server may be down.
>             The Web server may be too busy.
>             The Web server may be experiencing other problems, preventing
it from responding to clients.
>             The communication path may be experiencing problems.
> Possible Solution
>             Try connecting to this server later.

This is a small server with only a half dozen users and the server load is
on ~10%.

I've checked the web server access and error logs and the mail server logs
and can't find anything that would give me a clue as to what is going on.

I'm not a PHP 'person' to be able to dig into the code to troubleshoot much.

I've taken nearly a default install of UW and sqmail with few
customizations.

Does anybody have any place where I can start.  I was thinking that it was
the way sqmail was talking to the UW Imap server.  Maybe I didn't have a
setting in sqmail correct, as I can move mail around with an Outlook or
Netscape IMAP client without issue.

Any help is greatly appreciated

Thanks,
Nate
