Expiry problems...

[John S Cooper <John.Cooper@citrix.com>]

I use auto-expire and, as expected, articles are marked "E" for later expiry.
I also arrange for expiry to take place using the gnus-demon facility rather
than each time I exit the summary buffer (I originally did this when I used
nnml because expiry was noticeably slow for me).

However, since switching to nnimap, I now notice that many articles which
should have been expired (marked E and older than 7 days) are now displayed
with the ancient "O" mark when I enter the group with a prefix argument.

Any idea what's happening?  With nnimap, does expiry have to occur when I exit
the summary buffer for it to work properly?

I've appended the elisp I use below...

Thanks,
