Problem Summary: User can enter email addresses to a data base through a form. Most are validated properly by java script on client side, but a few users don't have java script and they enter incorrect syntax in an email addresses. The bad email address goes into the data base and when a CFMAIL is processed against a query loop it chokes and hard fails on the first incorrect mail address format it encounters. Possible Solutions: I see a couple possible solutions: 1.  On an MX7 server I could use the new IsValid tag in the loop, however, the site is not on an MX7 server, it's on MX6. Bummer. 2.  If there was some way to make CFMAIL not choke on bad email addresses and just process through them that would be fine, but I can see no way to override the halt. 3.  If there was a script to validate on the server side I could use it. I found a custom tag an macro media site which does do server side validation for email at: http://www.macromedia.com/cfusion/exchange/index.cfm?view=sn131&extID=10 24332#loc=en_us&view=sn131&extID=1024332&viewName=ColdFusion%20Extension &avm=1 but the download gives a 404 error. HELP NEEDED: Bottom line is I need to either: 1) validate the format of an email address and, if it will not choke CFMAIL, let it run, or 2) tell CFMAIL not to halt and continue on when it gets a bad mail address. Does anyone know of a solution for this problem? Thanks, Robert B.
