I have all the settings that are settable for different scenarios.
But that's what firewalls do, they block ports.
Then you program in "exceptions".
Do start / run
firewall.cpl
and you can look at the exceptions tab.
Then, if you have your own 3rd party firewall..you have to program
exceptions into that.

Thanks for the reply. Does all applications that are developed with the
.NET Framework require end-user's to reconfigure their firewall just to
send email?
It would seem absurb to me as many applications send electronic mail with
Antivirus Software installed and no configuration is required - the mail
is scanned and sent.
Thank you for your time.

>Hello,
your antivirus package may include a personal firewall which blocks
outbound communications on port 25 (which is usually used for email
communication).
If this is the case, you need to reconfigure the firewall.
Kind regards,

>>Hello,
I am writing an application that processes and sends electronic mail
using Visual Basic that has no issues as is.
However, when running concurrently with an antivirus package that is
installed (such as Symantec Antivirus Corp. Client) any mail that the
application sends the message is only delivered AFTER my application
closes or if the antivirus software is disabled.
Since my application will be deployed to a variety of system I do not
want to require the client to disable the antivirus application just to
use my application.
I have tried to call a new thread to perform the process in the hopes
that when the thread finishes the emails will be sent but this does not
occur. Is there anything that I am missing? How is this accomplished
normally?
Regards,
Christopher Koeber
