I've got a bulk e-mail script which connects to a local smtp-server.
But when an e-mail is sent to an invalid e-mailaddress, the following error appears:
450 4.1.2 : Recipient address rejected: Domain not found

The following e-mails get the same errors, although they are correct.

This is the smtp-debug:
C MAIL FROM:<newsletter@xxx.com>
C RCPT TO:<recipient@invaliddomain.com>
C DATA
S 250 2.1.0 Ok
S 450 4.1.2 <recipient@invaliddomain.com>: Recipient address rejected: Domain not found
Disconnected.


What to do? Is the correct way to start all over and reconnect?

You may carry on because each delivery is independent.

Thanks for your quick reply.

The messages aren't sent after the disconnected-message. They all get the error:
450 4.1.2 : Recipient address rejected: Domain not found

Even though the e-mailaddresses are valid. So how do i carry on?

It is returning the previous error. Just set the error variable to an empty string.

Doesn't help.

Messages aren't being sent.

This is the stripped code. I couldn't find a good example for a bulk html e-mail with alternative text so I created it myself, perhaps it's incorrect?

You need to set the class error variable ($email_message->error) to an empty string. You are setting a local variable instead, which obviously has no effect.
