Blocking mail function in PHP
I have been using popular subscribe 2 plugin to send message alerts by email to subscribers when a new post is made to site. However only some people receive emails when a post is made. Everyone appears to receive the test emails and alerts when they've been assigned a user name/password perfectly. This leads me to believe there is prob with PHP portion? I've installed an smtp server plugin, but same problem occurs.
Here is error message that site administrator email address receives when the email can't be sent: (I've placed ### marks in place of recipient's name in receiver's email address). Any thoughts on why this would be randomly happening?
