My WordPress Blog is hosted by Yahoo. The blog is up and running well. I wish to enable posting by email, which is set up per the posting by email documents on this site; http://codex.wordpress.org/Blog_by_Email
I always get the above error whenever I run http://example.com/installdir/wp-mail.php
For certain, I have entered the pop3 info, user ID, and password correctly in the Blog setup, and the email account works and is active, and I can access if via pop3 by other means.
I have searched and read every document that I can find, with no clue as to what this might be.
Please can anyone help?
