Fix email address error from email parser

Recently i discovered that the email parser i'm using is not giving me a perfect email address.

Here's some example:

@.comea (it should be .com)
@.sgor (it should be .sg)
@.asiaplease (it should be .asia)
@.com.sg.data (it should be .com.sg)
@.netr (it should be .net)

Is there any code snippet in php to fix this issue? Appreciate your kind help and thank you in advance!
