Description:
------------
php.ini-dist and php.ini-recommended contain following bad line:
sendmail_from = me@localhost.com

The domain localhost.com is a regular registerd domain and shoud not be used as default from.

You should change that line to: 
sendmail_from = me@example.com
(see also RFC 2606)

The main problem is, that some smtp server reject this 'from' because localhost.com and ghost.localhost.com (MX)gets resoved to 10.11.12.13 which is a LAN-IP Adress.

Another problem are bounces caused by users passing a non existing email address to a web formular. 

I'm sure you can think of many more examples ;-)

Changed to "me@example.com" and commented the option out.
(people REALLY should modify php.ini :)
