Mobile Feeds Help TWO
With regards to Anti-Virus/Firewall Suite Software, what causes a problem is software that does not allow programs other than the registered Email programs on your computer (Outlook, LiveMail, Eudora, etc) to send outbound Emails.
I am not familiar with many of the multitudes of antivirus/firewall programs in existence, so I will attempt to tell you how to locate the proper area to allow you to make an exception for MagicWebFX outbound emails or worst case how to turn off outbound scanning.. If you consult your program's help file, you can search for any of the following to attempt to find a solution point: email / email exclusions / email scanning / outbound email. You may also have some success consulting the manufacture's web site and/or their sponsored community forums.
I personally use ZoneAlarms and the picture below shows where/how it denies outbound Email. The first time MagicWebFX attempts to send, ZA alerts and asks me if it is permissible and allow me to make a permanent exception.

This website references a possible Norton/Symantec solution.
This website references a possible McAfee solution.
Any contributions in the form of successful solution links and/or screen shots would be greatly appreciated.
