Mails are not expired

[Nikolaus Rath]

Hello,

I have a nnimap group with group parameters

((uidvalidity . "1148224209")
 (to-address . "work@pulse-copy.com")
 (subscribed . t)
 (broken-reply-to . t)
 (total-expire . t)
 (expiry-wait . 14)
 (expiry-target . delete))

yet the group contains (read) articles from before March 21. Why
aren't they deleted?

Thanks in advance,

  --Nikolaus
