Wordpress 2.3.1 not sending emails error

This has been an issue that I have yet to resolve in my blog. Ever since I upgraded to wordpress 2.3.1, I have not received the emails that wordpress should be sending me. Here are the symptoms that I’ve noticed for this error.

• WordPress is not sending out comment notifications.
• Those who subscribed to comments, don’t get notifications of new comments.
• No mail is being sent out by the wordpress database backup plug-in.

So what do we do with this error? I have tried different solutions that has been suggested but all I got is a temporary workaround. Although I wanted a permanent fix, as for now a workaround is better.

Here are the temporary solutions that people has claimed to have worked for them. So just try each of one to know which one will work.

#1 Make sure that wordpress@yourdomain.com is a real email address.

You can create a new email account in your cpanel. (Ticket 5294)

#2 Remove line 228 from the file wp-includes/pluggable.php.

Remove this line -> $phpmailer->Sender = apply_filters( ‘wp_mail_from’, $from_email );
or you can use a plug-in where you can get from Ticket 5294.

#3 Install a wordpress plugin called WP-Mail-SMTP

Download it here. Configure it to use SMTP instead of the php_mail() function.

I’m currently using solution # 3. I am able to receive comment notifications but have yet to know if the comment subscribers are receiving comments.
