Absolutely not. You CANNOT break running code like this.
That should not break running code, but merely highlight that SENDMAIL
and EXIM didn't follow a 25 year old RFC 821 specification to begin with:
In many cases the sender-SMTP then simply needs to search for
the reply code followed by <SP> at the beginning of a line, and
ignore all preceding lines. In a few cases, there is important
data for the sender in the reply "text". The sender will know
these cases from the current context.
It makes them non-compliant. I think the NEW sentence for the NEW SPEC
should include a clarification such as:
The client SHOULD use the final line as the ultimate
and it would be still be inline with a 25 year old SPEC.
The next question is whether SENDMAIL/EXIM is going to fix their code.
:-) Which BTW, are you referring to current versions or old versions?
and you referring to just "150-" or "150 " when you say it breaks them?
