Hello all,

It happened a few times already that a member not wanting to receive any emails from the server goes to the personal information page and changes his or her email address to an invalid one.

I have to ask you to not do this, if your email address is invalid all the messages that the server sends to you will instead bounce back to the server. That generates extra work for me, because I have to clean up those emails myself periodically.

The server allows you to disable all emails sent to you in the <a href="email.php">Email Options</a> page, this is a far more polite way of telling us that you don't want to be bothered with email.

If I continue seeing this behavior I will have to institute an email verification system for everyone who changes emails. You will get a message on your new address with a code or something that you will then need to give back to the server as proof that you have received the message. But of course I prefer to spend the little time I have adding features to the site and I'm sure you prefer that too, so please make sure your email address registered with us is valid please!

Thanks.

Miguel

Hello,
Can't you verify with the server email that's a good email ? It's seem to remember me that's possible with php... I yet found some script wich do that...
Hum... I not absolutely sure, I try to find it.

(I don't try it and perhaps it doesn't work... but It seem answerd to your problem)

As far as I know there is no way to verify if an email address is valid or not in real time. The mail server will send out the message and the receiving server can take as long as it needs to process the email and if found invalid send a reply.

I don't understand how the script you found works. It appears that it sends a fake email to the address to verify, but since all these happens at the sender's server, it is only validating for syntactically correct email addresses.

There's a way to prevent this. Every e-mail change must be validated by secret a code sent to the new e-mail address. Until the user receive and validate the new e-mail address, the old e-mail continue working. As e-mail change is not common, it's not a really disturb for the user.

Sounds like a lot of work for Miguel though.

Since not everyone reads the forums (more fool them :-) ) why not put that request and information into the form where you change the email address, with a link to the email options page?

Not really a hard work. I had make this kind of validation in some projects and it's easy to implement and very effective. :-D
