open-xchange without maildomain

[be7a]

Hi,

I'm basically looking for an online solution to sync my laptop, cell and desktop pc in real time. (I don't want to sync them every day in the local network.)
A webmail client wouldn't be wrong, but isn't mandatory.

My idea:
Setting up an open-xchange server, OXtender and SyncML on my gentoo box. Then getting all emails from my pop accounts (gmx, gmail, ...) via fetchmail and putting them into my inbox. Then I can access this mailbox from my different machines (GUI: MS Outlook) and receive and send mails from my different accounts. I don't want to loose the information from which account the incoming mail originated. And I want to be able to send emails via different pop accounts.
Advantage: emails, calendar, contacts etc. are in sync and I don't have to sync them manually.

Questions: Is this idea right? Will this work? Is there another (better/easier) solution?

If using IMAP instead of POP accounts, you could use Evolution to pull down the IMAP inboxes and Evolution lets you send as different accounts as well.

Probably not what you're looking for but figured I'd throw that out there.
