Wireshark-users: [Wireshark-users] Mails bigger than 192kB are timing out.

Date: Fri, 29 Jun 2007 04:33:46 -0500 (CDT)
Hi,

I have an issue between the connection of a client to a mail server. The
mail server works fine and it can process messages correctly. The client
works fine too and there is no problem to send emails using other mail
servers. However, when I try to send an email using this particular email
and the attachment is bigger than 192kB, the connection is timing out and
the email cannot be send. Here is a part of the wireshark log. I would
apreciate if someone has an idea what could cause this issue.
