Charlie, Thanks for your post.
I have determined that I haven't been black listed, and I think a lot of this is spam detectors. Yahoo and GMAIL were GOOD in letting the mail go through once they were "told" to accept the email address. I am sure that we are on an earlier version of CF, but I am not sure which one. I tried putting a wait as was suggested in an earlier post but whatever version that I have does not support the CFOBJECT. I checked your BLOG and it was helpful in understanding the issues and message ID. I am using a hosting site. Is there some way that I can figure out what release they are on?
