Hello,
I am trying to understand what I need to do to prevent emails from
going into the junk folder. Leaving consent aside, here is what I've
found so far:
1. Return-Path and From should have valid email addresses;
2. Better have the recipient NAME together with his email address;
3. Plain text email is reportedly safer than HTML;
4. Use HELO protocol (still need to figure out what this is and if I
can use it with PHP's mail() function);
5. Remove the X-Mailer header (saw this recommendation in some posting,
not sure if true).
Would very much appreciate additions to this list. E.g. should I have
the MESSAGE-ID header and why?
Many thanks in advance,
DR
