I've decided that we desperatly need to switch from POP3 to IMAP when handling our main business email account which several people use. This is your typical firstname.lastname@example.org account which receives pretty much everything from customers, suppliers, business partners, etc. The email is provided by our hosting and they use qmail. Any server-side configuration that we are allowed to do is through the Horde web mail interface. Our local email client is Outlook Express.
One of the major problems that we've had is that we can't see if an email has been answered, deleted (spam), etc by someone else. Another problem is that each of the four client setups is using its own email folder structure, so it's always a pain to work on some else's PC.
So my questions are:
- How do I setup IMAP (client and server) so that every client using the same email account has the same folder structure.
- Our server mail setup doesn't support email rules ("if sender is foo, move email to Important"), so there is no way to centrally and automatically send emails to certain folders. Is there a way to solve this? We are using Outlook Express on Win XP PCs, but I rather not create the rules on each client as this is cumbersome to maintain.
Addendum: Should we migrate from Outlook Express to another client that isn't tied to Windows (we're currently using Win XP on all PCs)? I mean, Outlook Express has been replaced by other software in newer versions of Windows so using, say, Thunderbird might be safer?
