It’s not Yahoo – wp-email/contact problem

OK…if you’ve read my earlier post, I’m sorry.

I’ve been trying get wp-email (and wp-contact form to work though I’ve given up on later) for days.

The problem is when I try to use the “Email This Post”
function, the email ends up in an error log.

It only works when I put webmaster@mysite.com in the “Email From” space.

All other email addresses end up in error log. I’ve tried it under PHP and SMTP settings and those fail to send.
SENDMAIL setting indicates that the post was emailed, but unless sent by webmaster, it too ends up in error log.

I contacted my host Yahoo, ad they allow all three types of mail and say nothing is being blocked.

I get the error message: “From address not in member domain. Message not sent.”

I don’t know what else to try.
