I've recently upgraded from a Sun3 to Sun4, and while Andrew (R4 beta
release, patchlevel 6) seems to be working pretty well in general, I'm
seeing an oddity that I don't think I've seen mentioned previously.

The oddity is this:  Sometimes, when AMS reads in new incoming mail, it
builds the "captions" wrong -- in particular, it completely omits the
sender's name from the caption, which therefore consists only of 

Date Subject - (size)

Now, the oddest part of this is that it is not consistent, but that it
affects all incoming mail read in a single chunk.  That is, if I have
ten new pieces of mail, either all ten will have "correct" captions or
none of them will.    So the variance doesn't seem to be on a per-mail
basis, but on a per-mailbox-checking-incident basis.  I haven't had a
chance to probe the code yet -- it looks painful, since it isn't
reproducible -- but I was wondering if anyone else had seen this problem
or had any ideas about how to fix it.  Cheers.  -- Nathaniel
