It begins with 250 2.6.0 and ends with 250 2.1.5. Why are there 2
status
codes? Does the second one provide additional context, maybe something
like
"not blackholed"? Or is it just repetitive and therefore
insignificant?
It's a very bad idea to seek consistent meaning in anything after the
standard SMTP reply code and (if present) the extended reply code in any
SMTP response.
I'm sure that every character in that reply has some significance to
Microsoft. Unless you can get a commitment from MS to maintaining a
particular meaning for a particular pattern AND you have some
inscrutable reason to trust such a commitment, you should not bother
trying to read the tea leaves.
