Setting up blacklists and spam filters is a tricky business
Seems this lady was getting her email blocked because her name was Gay
I am sure this happens a lot
QUOTE: It seems NZ Telecom has an email filter in place to prevent abusive emails reaching their staff. That's fair enough, people sometimes write the most astonishing things in email (that they probably would not say on the phone or put in a letter) and it's quite right for a company to refuse messages that go beyond polite discourse.
Whomever configured this filter went overboard in their definition of 'bad' or 'inappropriate' words and it's a lesson to anyone who has such a filter. You need to be especially careful with words that have multiple meanings like 'gay'.
