Email does not get checked at registration?

Again. Bug or feature?

It looks like that there is no email validation in the user registration. A user who entered a not vaild address would never receive a confírmation mail.

Thats the point.. if you have validiation turned on people who don't put in valid addresses can't join.

If a user makes a mistake in their email address the admin can activate the account by hand..

Well ok. But it would be easier to the user and the Admin if there is an email "spell check" that checks the email for "anything allowed here" @ "domain" "dot" "anything allowed here".

So then i only have to check those users who entered a wrong address and not a misspelled. I don´t talk about a DNS check or something. Just "spelling".

You cant make a spell checker for a mail. Because it is all names, so the only thing that can be checked is if there is a @.

Andre,

You are highly mistaken!

I have a function that does the:

"anything allowed here" @ "domain" "dot" "anything allowed here"

validation. It works like a charm, and next to checking for valid server (which I have a function that will do that too) this is the best way to validate an email.

Personally, I think the whole idea of -not- doing an email validation is crazy!

Two points ... firstly if someone is out to deceive an email validation system they'll input a syntactically correct email address ... just not a valid one.

Secondly doing an MX lookup tells you nothing more than the server exists (or may exist ...), it doesn't tell you if the user exists on that server. It's a falacy to believe you can fully check an email address without actually sending something to it and asking for a response. Which is of course what we do with email activation.

Incorporating a simple preg check can be done in seconds, it's not exactly complex programming ...

Thats all I am asking for. A simple preg check. There are enough users out there who are not able to type a syntactically correct email address (Look at all those AOL users)

. I think everyone running a site made this experience.

Those Users will never know what they made wrong and why the will never receive a email from the system.

A little Javascript may do the trick as well. That would take the strain off the server.

Well he is talking about a SPELL checker not a server host checker. Or do I mis samething here?

He's looking for a check of well formedness, ie. ^.*?@[a-z0-9]+\.[a-z0-9]+(\.[a-z0-9]+)*$

Well I think that if you checked for the existance of the server you will take care of both problems. I know that the existance of the server doesn't garantee that the person receives mail there. That is why I use a double opt in validation. At least if the enter an incorrect domain name they are stopped before it is submitted and warned of that fact. Saves me the trouble of deleting all those accounts that were never activated.
