SPAM Problem
-
Hey My site uses System.Net.Mail to send out confirmation mails after registration. When I check the mail's spam score, I alway get "Bulk email fingerprint (X-Message-Info) found" and its spam score alone is 3.5. How do I fix it? Thanks.
That depends entirely on the spam engine of the RECEIVING smtp. Maybe it is the wording of your message that triggers this. To be honest, most confirmation mails that I get from reputable sites end up in the junk mail when using google mail or hotmail. So you're not alone in this. Things you can check on your side: -The IP address of the sending smtp server should have a reverse DNS entry (in-addr.arpa) -It may help if the DNS domain from which the mail is sent (or appears to be sent) contains an MX record. -Try not get blacklisted :-)
