I read in "Managing IMAP" that Cyrus can be configured to keep
only one copy of a message that would otherwise be duplicated
many times. For example, if 10 people are on the same mailing
list, only one copy of each mailing list message would be kept.
How does this work? And how well does it work? The book said
that Sieve was involved, but I'm not sure why that would be the
case. For example, if someone copies a message from one
folder to another, that would result in a duplicate message, too,
and Sieve wouldn't be able to handle that, would it?
Thanks!
