I've used the POP3 component to download all UID from a POP3 server and only
download messages to a local database which have not already been downloaded.
This seems to work quite well.
However I'm struggling to see the 'higher level' view of how I could synch my
database with the IMAP server.
I've used the Search() method to find UNSEEN messages or messages SINCE <date>,
this is OK, but with IMAP I have to be able to synch the entire folder because
the user could have replied to an email from (say) 3 months back.
Surely I don't want to download ALL envelopes? Or should I download all the
message headers, will they include the UID?
Can I have some advice on how I could synch to an IMAP account with a local
database?

Downloading all the envelopes should be fine, as long as you specify only particular envelope parts you require. In your scenario,
that would be just EnvelopeParts.Uid and maybe also EnvelopeParts.Flags:
Code:
EnvelopeCollection envs = imp.DownloadEnvelopes(Imap.AllMessages, false, EnvelopeParts.Flags | EnvelopeParts.Uid, 0); |
|
|
This would get you the envelopes list, each of those comes with Uid property of course.
