Hi
Duane,
Can
you find some lines containing "send error 10054" (SMTP) or "send error [IP]
10054" (POP3) in your logfiles?
This
is happening on our server (ver 7.15) several times any day and was already so
on ver 6. Any time the IMail-Server has dropped the SMTP- or POP3-connection
to the client. The client has his timeout (usually 60 seconds) after them he
returns an error message.
As I
has understand in several tests from different clients, connection types and
connection speeds this happens any time if a client (any client!) connects
over a slow (or satured) line to an IMail-Server. If some TCP-Packets has
delays greater ~7500 to ~9000 milliseconds the mailserver silently drops
the connection to the client and writes the 10054-error in his
logfile.
Until now I haven't found any solution for this. I've
tried to set up a POP3-Proxy beside the IMail-Server hoping that this can
level out the high delayed packets from the client. Unfortunately without
the desired result.
I
assume that IMail ver x.x has a hardcoded timeout for the next TCP-packet. If
the time between two packets is greater then around 8000 milliseconds the
connection will be dropped.
I'm
pretty sure that this has absolutely nothing to do with certain motherboards,
NIC's any other hardware or windows server settings. In the same time that
certain clients (with a slow connection to our server) has the timeout
problems dozens of other clients can send and recieve messages like
a champion.

Hi
All,
I have one
client that is having issues trying to
email out using Outlook. When they send out files 1mg+ the email gets to 85%
done and then hangs up and they get timeout errors. I am running Imail
V8.00.
I've gone thru everything I can thing I can think
of:
- Removed incoming and out going email
size limits
- Upgraded to V8.00 (from
7.07)
- Freed up disk
space
- Rebooted the server (nothing else worked
so....)
So far nothing has
helped.
Any ideas what I should try
next?
TIA,
Duane
