I just realized that my blog is not sending out new registration emails, and also doesn't send the password reminder email. with registration - it looks like it goes through just fine - i get the message saying "registration complete"
with password reminder, i instead get this error:
"The e-mail could not be sent.
Possible reason: your host may have disabled the mail() function..."
i went into the pluggable-functions.php file, and replaced the line:
"From: wordpress@" . preg_replace('#^www\.#', '', strtolower($_SERVER['SERVER_NAME'])) . "\n" .
with my email address, but still no luck.
any suggestions? i seem to remember fixing this once before, but can't remember what i had to do....
