[Evolution] question re evolution-mapi and messages marked for deletion

[Reid Thompson <jreidthompson nc rr com>]

i consider evolutions normal 'messages marked for deletion' handling to be along the lines of
1) select msg for deletion
2) mark msg for deletion
3) depending on setting, message will either be visible in inbox with strikethrough or message will be hidden 
in inbox and message will be visible in Trash
4) expunge will delete message

is this the way it's supposed to work in MAPI?

what i am observing is
1) select msg for deletion
2) mark msg for deletion
3) depending on setting, message will either be visible in inbox with strikethrough or message will be hidden 
in inbox but only for a short period of time
4) after short period of time (sometimes almost immediately) message will not be visible in inbox regardless 
of settings
    message will be found in Deleted Items folder
5) expunge will delete message
