Hi, Ryan, Usual disclaimer: "I am no expert, and am not even friends with an expert!!" Assuming that the email is sent to a single user at a time (which is what it sounds like you are doing, because many sites will filter out email with no To: field), other things that can be easily filtered include whether the sender domain matches the smtp domain, on the premise that spammers may use a promiscuous smtp server that is not of their own domain (or forged domain). For example, if you where sending email with the user.r configured name of [jblow--mysite--dom], but sent the email through your isp's smtp server of say smtp.myisp.dom, then the site may filter and block this type of email. A solution is then to be sure that the sender dom and smtp dom match. Other things that can be filtered are by the sending email client. Sites like Earthlink (nee Mindspring) imply that they may filter based on clients that are known spam generators. If you suspect something like this, then you can create email with a custom header that either leaves of the name of the email program, or uses a more generic description, like that found in Netscape. Hope this helps. --Scott Jones
