Finding that mail sent via is not being accepted? The problem could be related to spam filters – because ColdFusion makes it so easy to send mail (even bulk mail) some spam filters block any mail that was generated by ColdFusion. How do they know that ColdFusion generated the message? By looking at the message headers, specifically the X-mailer header (which by default reads “Allaire ColdFusion Application Server”, a dead giveaway). The good news is that you can change this header quite easily – just use the MAILERID attribute (or ) to set your own value (perhaps your URL). (Applies to: ColdFusion 4 (or later))
