Right.

MU_ATTRIBUTE_READ means the user has read the message, i.e. he has
accessed its headers and/or body in some way.  The 'S' suffix, according
to [1], means "the user has viewed this message, though perhaps he
didn't read all the way through it".  This looks pretty much the same
thing, indeed.

It looks so.

In IMAP, the absense of MU_ATTRIBUTE_SEEN is equivalent to \Recent, and
vice-versa: the absense of \Recent flag means MU_ATTRIBUTE_SEEN is
set.
