HOWTO Check failed emails

[CMan]

Hi,

I need to check emails from a web application. Is there a simple way for the
application to check whether an email arrived?

Thanks

I don't know about that. But it is possible to check whether an e-mail
address is valid using a chatmail server.

Thanks for your response but I would also need to know if there were
failures going to valid email addresses.

Thats not a "chatmail" server, just connecting the the domain's MX
server and trying to see if the email is allowed to be sent there. If
the email is a correct email address, the domain's MX server should
allow it through.

But it opens another can of worms. What if the MX server is currently
down? What happens if it uses greylisting and initially will block an
incoming connection to reduce spam? This in my opinion is not the best
way of doing this.

Once the mail has left your smtp server, the only way to check if there
was a failure is to create a mailbox for the email address you are
setting as the FROM: parameter in the email. You can monitor the inbox
for bounces and log from there.

You have no control over what happens to the email once it leaves your
servers.

Hope this helps!

Thanks Ray,

Maybe the 'Grumpy Programmer' approach is to tell them to get the new kid to
check the mail box every morning

Haha, probably.
