I was thinking of reviewing the basic and enhanced status codes that I
am generating, because I would like to have more insight into at what
stage, what code is being generated.
For instance I am using the 550 5.7.1 for dns blacklists, but also for
spf hard fail. I am also soft failing messages @gmail.com / @outlook.com
with this status.
The accompanying message describes clearly what is going on, but this
message is sometimes not relayed back to the sender. Even worse is, if
only the 5.7.1 code is relayed back to the sender (thus without my error message) with some huge manual on how to setup spf. Afaik is 5.7.1 not
really specific to spf.
Q2. Am I allowed to start reject mail on codes like this:
599 5.0.11 dnsbl spamhaus
599 5.0.12 dnsbl spamcop
For the spf I can use 5.7.23. But when I reject a message from xxx@outlook.com not originating from outlook.com spf servers. I do not
want to use this code because, I do not want outlook.com to reference
some manual about the spf hard fail.
Q3. When should I use a 'correct' status like 5.7.25 for reverse lookup failed and inform spammers how to set up their spam environment, or just
Q4. What value do these status codes still have.

Isn't all the information in your logs?

"soft failing" with 550?
Q2. Am I allowed to start reject mail on codes like this:
599 5.0.11 dnsbl spamhaus
599 5.0.12 dnsbl spamcop
599? No....
X.0.0 Other undefined Status
doesn't make much sense.
599 5.0.11 dnsbl spamhaus
599? No....
X.0.0 Other undefined Status
doesn't make much sense.
So there is no way of using unique status codes, so I know just from the
code what happened?
