Guys
please please state which email solution you are using when you explain the problems you have. Modest as a client certainly has some limitations, but is it a Modest problem or the protocol or the server, or the way you have set it up. So please state:

are you using MfE or Nokia Messsaging, or IMAP/POP to access your server.
what is your back end service ? ie gmail, yahoo,exchange. If exchange, what version.

some of the problems here are known, some have fixes on the way, some are configuration, some are server side.
