[Dovecot] mailbox sorting issue

[Paul]

Thanks for the "junk at end" help. Now I'm having one more perplexing
issue:

When I sort a Dovecot mbox in Pine, the most recent messages tend to
linger near the bottom of the message list, regardless of how they're
sorted. Here's a snippet of the bottom of the list, sorted by arrival
time:

And here is a snippet of the same mbox list, sorted by From address:

Notice that message from cm2144 in both lists, way out of order in the
second!

I'm not 100% sure that this is a Dovecot issue, but I suspect it is,
since this doesn't happen if I open the same mailbox locally or with
UW-IMAP. I know that Pine makes use of IMAP server-based sorting if it
is available.

I tried deleting .imap-index* files, just in case, but that didn't help.

thanks,
