[Kolab-devel] Feature-request: Recall locally delivered mail

Hi,

some of my users are asking me if there could be a recall feature for 
locally delivered mail. Could it? If yes, this should only be possible 
as long as the message remains unread by all recipients and present in 
their inboxes (one would have to examine the read-flags of the message 
for those users).

Alternatively, one could some delivery-delay feature (hold the mail in 
cache some user-set time before delivery) to realize a recall-feature?

Best regards,
Henning
