Everything was working perfectly a few weeks ago and all of a sudden (bam!) something is now blocking our online forms. We do host our own website on separate server within our network. As far as I can tell nothing has changed on the web server.
What happens is when a somebody goes to submit a online form in any browser (IE, Mozilla, Chrome...) they get the "Server Error: 500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed."
Could our email server be blocking these forms?

P.S. I've already checked with GFI MailEssentials and the said; "All Mail Essentials does is scan the mail. There should not be any affect on another servers web page".
