Betty, it appears that your ISP uses a very restrict SPAM filtering routine.I have tried sending the information thru two different ISPs and one being Earthlink but both were rejected.You might check with your ISP.
firstname.lastname@example.org SMTP error from remote mailer after RCPT TO:: host mail.elc.net [220.127.116.11]: 553 5.3.0 ... Spam blocked. See: see http://dsbl.org/listing?ip=18.104.22.168http://dsbl.org/listing?ip=22.214.171.124
Go to the second URL above and it explains what's going on.
The information I'm trying to send is Texas Vital Record information. Hugh
