How to Fix Mediawiki Confirm Account Extension Error qmail-inject: fatal: unable to parse this line:

Question

I have an instance of mediawiki installed with an extension called Confirm Account. This works fine on my MAMP setup at home. On my MediaTemple.net account I get this error when the extension is run:

Error sending mail:Unknown error in PHP's mail() function.

The server error log error is:

qmail-inject: fatal: unable to parse this line: Return-Path:apache@ 216.70.110.23:7081

I have no idea what to do to fix this. Thank you.
