I have some weird problems with email bouncing for a catch-all account.
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
Whilst majority of the email sent to anything @test.hello.com works and goes through the PHP script, some emails sent by some servers bounces with this problem:
Hi. This is the qmail-send program at xxxxxx.xx***********.
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.
18.104.22.168 does not like recipient.
Remote host said: 550 No Such User Here"
Giving up on 22.214.171.124.
I'm not sure why it gives a 550 No Such User Here error here when it's suppose to be a catch-all account?
Thanks in advance,
