If you are unable to send mail using your
desktop email client, begin by reviewing all of the
instructions for configuring your desktop client to insure
that you haven't missed a step.
If everything is accurately configured
and you still can't send, and if you have anti-virus
software such as Norton or McAfee enabled, trying turning it
off. If you can send when it is turned off, it is because
your a/v software has changed some of your secondary email
If turning off your a/v software doesn't
solve your problem and if you are running a personal
firewall such as Zone Alarm, try turning that off and see if
you can send mail. If you can, you will need to change your
Zone Alarm settings, as they are interfering.
If you are still unable to send, try
turning off both your a/v software and firewall
If you still can't send, you can you try
to test your connection tou our server through "Telnet". If
you're not familiar with the way Telnet works, here's a
Telnet is an application contained on
"most" Operating Systems allowing you to connect via
"Command Line" to a particular server. In this case, we will
be attempting to connect to www.cotse.net on port 25.
In Windows, you may run "Telnet" by going
to Start --> Programs (and then sometimes "Accessories"
(it depends on your version of Windows) then click the MSDOS
or in some instances, the "Command Prompt" icon. When this
window opens, type: telnet www.cotse.net 25
This should connect to the www.cotse.net
smtp server on port 25. The return value present in the
telnet window should look similar to:
220 www.cotse.net ESMTP
CotseMail 5.7.4/5.7.4; Wed, 17 Sep 2003 23:29:53 -0400 (
If you see this, chances are, your
connection to our server is good. If you cannot see this,
chances are, something is blocking your connection. This is
a good indicator whether you can connect through your
desktop email client or not.
If after conducting all these tests you
still cannot send mail, please email
us and tell us what desktop
client you are using, what settings you are using, what you
have tried and with what results. Note that we do not
support all desktop email clients, but we will try our best
to help you.
