I still do not understand why the expiry mark "E" disappears from the
articles in my spam group. 
 
I set up my spam group so:

(add-to-list 'spam-junk-mailgroups "nnimap+localhost:spam")

When I get mail, procmail splits it and puts the spam in a "spam" mbox
file which is one of my IMAP folders. (I use the crm114 spam filter and
the dovecot IMAP server)

Now when I go into the spam group in Gnus (that is the "spam" IMAP
folder), all new spam is marked as spam ("$"). When I exit the group and
then open it again after a short time, I see that the same articles
which were marked as spam are now marked as expired ("E"). But when some
more time passes, and I open the spam group a few more times, I see that
the "E" mark has disappeared from the older spam articles - so my spam
group keeps growing.

The Gnus documentation says that expired articles are deleted after some
time - but in my spam group expired articles become "unexpired" again,
and so far I haven't found out why this happens.
