As Patrick says, if your IMAP server is working properly, there should
not be any need for Evo to download all the message summaries every time
it connects, unless somehow your local cache is getting deleted.  IMAP
assigns a monotonically increasing message ID to each email as it's
received and clients have the ability (at least this is how I understand
it: note I've never actually implemented an IMAP server or client
myself) to request information on messages with ID's above XYZ.

So the client is able to cache locally the information for older
messages and only need to retrieve information for newer messages.
Anyway that's how I understand it to work.


You don't say what ISP you're using.  I've had issues with accessing
GMail over IMAP, myself.  I don't know what their IMAP integration does
but Evo sometimes does not notice new mail for hours (if I go to gmail
via my browser it's always immediately visible there of course).  Other
times it works fine.  Also access seemed very slow: I modified my GMail
account to unsubscribe from the "All Mail" folder and that helped quite
a bit.
