Stefano Bagnara commented on MIME4J-60:
---------------------------------------
Sorry if I've not been able to explain the flaw I was seeing. But in the end we
understood, and this is the important thing.
About the isolated CR, I'm not in love with them.
I keep asking this because I know in JAMES Server code the CURRENT behaviour is
to translate them too. So, if we ever think to use mime4j instead of the
current code in JAMES Server we'll have to deal with this issue.
I don't have the needed knowledge to understand what are the real use case of
agents using isolated CR, how often does it happens and why.
Can anyone help understanding if this is an NON-issue I'm inheriting from JAMES
Server codebase or if there is any requirement behind this?
I've searched the internet for various implementations but I didn't find
anything giving me more deep understanding. If we consider the LFCR sequence I
found implementations that thread it as:
LFCR (not altering them and only using LF as the newline)
CRLFCR (only altering LF to CRLF)
CRLF (consider the "inverted solution" as a valid delimiter)
CRLFCRLF (convert both to newlines)
None of them converted only the CR: I think this is the only missing behaviour
:-(
For the record (and fun) maybe this 1987 message is the root of this issue:
