Most clients are incredibly stupid. Most of my time spent supporting
JavaMail is spent finding bugs in servers that don't cause problems
for any other clients, which of course leads people to believe the
bug is in JavaMail. Most clients just treat IMAP as a glorified POP.

4.1.3 is worst for clients that try to do the right thing. I guess
4.1.2 is worst for stupid clients, which sadly is the majority.

I'd be happy to have both 4.1.2 and 4.1.3 declared as not allowed

What a shame there isn't a test suite to test conformance with the
IMAP spec...
