Email piping problem for some servers.

[darkshadow604]

Hi,

I've set up a catch-all email account that pipes into a PHP file - lets' call this *@test.hello.com which pipes to |/home/test/test.php

While majority of the servers work when you send to [email protected]. Some servers have their emails sent to [email protected] bounced.

Hi. This is the qmail-send program at xxxxxx.xxxxxxxx.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<[email protected]>:
123.123.123.123 does not like recipient.
Remote host said: 550 No Such User Here"
Giving up on 123.123.123.123.

Why would there be a 550 error when it's suppose to be a catch-all address?

Could it be because of qmail? I don't have experience with qmail, but servers that worked used postfix when sending the emails.
