Should a system that gives the following response to a SMTP request give a
code 450 error or a code 550 error (I did think a code 550 should be given).
(host mxfilter4.domain.net[70.34.y.z] said: 450 4.1.1 <userdomein.nl>:
Recipient address rejected: undeliverable address: host
mail.domein.nl[70.34.x.y] said: 550 "Unknown User" (in reply to RCPT TO
command) (in reply to RCPT TO command))
I did change domain names and the email address and IP addresses (as they
aren't needed in this example and pointing to someone is also something I
don't want to do).
Is what I suspect correct or are I wrong?
- it gives a 450 error code (while it receives a 550 error code)
I think it should be:
- it should give a 550 error code (because it did receive a 550 error code
from a server downstream)
With kind regards,
