Try replacing the test with this:

if( preg_match( '/@(mailinator|binkmail)\.com/i', .....

preg_match() returns the number of matches, it will be zero (false) if there are none. [1]

In addition the pattern is now case insensitive and the period is meant literally.
The "end of string" specification ($) seems superfluous and could cause trouble.

Hope that helps.
