Outgoing: The VPN won't let
IMSmail connect to remote domains to send mail. Is it possible to setup
IMSmail such that it uses an external SMTP server, and is it too late for the
ones failing to go.
Sure. Set the "gateway"
setting to the external SMTP server, and all mail will be forwarded
there.
Incoming:
1) I could setup 2
accounts for each user, and get Tbird to read both new and old email servers
until the old server is empty. I would then need to revisit the clients at
some stage to remove the redundant server account (and eventually the server
itself).
2) Or, I could process the waiting IMSmail and either re-send it
to the new server, or perhaps import it directly into Tbird. This has the
advantage that the users' setup would only need visiting once, and I could
disband IMSmail straight after the transfer.
Setting the "gateway" setting
will send *all* mail to the other server. That would seem to be what you need
anyway. Of course, mail already delivered to POP3 boxes is just going to sit
there. You'll have to do something by hand to get rid of
it.
