Well, if we consider that for a few years now unicode domain=20 names are a reality, it becomes useless to check the domain name=20 of the email address. It can be virtually anything. For example is a valid domain.=20 There are lots of new domains like .aero, , etc.... More on the subject here I think the problem comes down to the quality of coding. For email address= =20 checking a regular expression is used. Most coders just copy/paste some=20 regexp code without checking if it actually works as expected. So don't be= =20 surprised. I remember that some sites required "private email address" and rejected an= ything=20 that was free (yahoo, hotmail, whatever). I didn't experience this sort of = restriction recently, but it is seemed pretty dumb at the time. --- On Tue, 2/8/11, Herbert Graf wrote: From: Herbert Graf Subject: Re: [OT]IT Annoyances in this day and age!

After all, .me.uk has only been around since what, 2002?=20 > I know I've had mine since 2004... I doubt there is a "TLD list". My guess is they are simply checking the length of your TLD. The shortest you normally see a .com is 3 characters, so anything less they assume you either made an error or are trying to hoodwink them. For example, on many webforms that require personal information I put "fake" information, an example is for phone number I put 416-555-1212. MANY webforms these days detect the -555- and reject it.
