I am trying to reduce the number of spam email that is reaching our firm and decided to use at least one verification method.
I am not sure what methods out of the following three is safe to use:
A - Verify MAIL FROM address B - Perform reverse DNS lookup for connecting server C - Verify HELO/EHLO domain D - Neither of them
What I mean under "safe" is, that results the least amount of false positives.
I decided to do a poll in this group and at the end of the poll I will share the result with all of you.
If you want to participate in this poll, just simply send an email to the following email address:
[EMAIL PROTECTED]
and in the subject line of the message please indicate which valid email verification you use out of the 4.
(this is just a temporary email account, that I created for this purpose, I will delete it at the end of this week, unless someone will come up with other good ideas of doing a poll on.
To make my task easier, please write only the corresponding capital letter(s) in the subject line, nothing else, and don't bother writing anything in the body of the message because I will not bother opening the message.
Thanks, Geza
