But, my email address, a@…, does not work because I have only one letter to the left of the @ symbol and it doesn’t accommodate people with underscores in their addresses too. I used this instead. It handles .COMs and .CO.UKs, too:

/([a-z0-9._-]+?)@([a-z0-9.-]+)\.([a-z]{2,4})/;

Cheers,
Adam

The reason that 12345@email.com is shown as valid..is because you can actually have 123456 as your email name. It obviously depends on your mail server. Secondly, the reason something@email….com s shown as valid is because there is no way to determine how many ‘.’ are used after an ‘@’ sign. Somebody may have an email address ’something@something.mail.ac.uk’ (3 ‘.’s) For this reason, the only way to 100% validate the email would be to get php etc to run a DNS check on the provided email address and return the result.
Since actionscript is client-side we are limited to basic validation without the use of a server-side language.

Hope this answers your questions.
