Server error on emails

[mistypants]

Hi all,
A user of mine reported that he was not receiving site emails. I sent him an email through cPanel from the email address I use for the site ( contact@kh-vids.net ) and he received that one just fine, so it's an issue with my Xenforo install, not junk/spam filters like I assumed. I checked my server errors and sure enough, there were a few related to emails.

I've only received a few reports of emails not being sent so they are working most of the time. One of the errors I saw was just related to the email field being too long (bots were trying to register with some insane emails and got rejected), the other common one looks like this:

Zend_Mail_Transport_Exception: Unable to send mail. - library/Zend/Mail/Transport/Sendmail.php:137

  }
}

Any idea what's causing this?

There is no error log for the email I just tried sending my user (the above one is from a few days ago), but I assume the issues are related.

Only some emails fail? Basically contact your mail host or try a different mail server. Here is a guide for using Google as your SMTP server:
