Anyone out there know if Cyrus 2.2.12 has any problems doing server side sort
by date? We've noticed when our squirrelmail has the option enabled to do
server side sorting, that the dates are sometimes out-of-order on emails that
were migrated from our old system. The headers of the emails look correct
Cyrus's binary date field is delivery time, not sender's time.
And, migrating, is considered a delivery.
and when I disabled server side sort and let the client handle it everything
is sorted properly. We also have users using thunderbird and mozilla mail
with no problems, however I am not sure if these clients use the SORT imap
extension. Anyone with any ideas?
Client side sorting is based on the "Date:" field I suspect, instead of
the binary indexed data that the server has.
If you think that's annoying.. some mail agents I've used, show
the binary delivery date in the message index (!), but show the right
date when you go into a message and look at the headers.
I've not yet seen a patch to cyrus to make, at delivery time, store the
RFC "Date:" field instead. I suspect it doesn't exist because it might
get abused by people sending intentionally wrong date data, and the date
sorting would bust to a point.
