Ok, but that applies to hardware that you own as well.   Maybe you can
beat Google for redundancy, reliability, distributed backups, etc. but
it won't be easy.   And with a simple imapsync or maybe even some
tweaks to your sylpheed setup you could have both.  That is, use
google for live access  but keep a mirror copy.  My guess is that your
disk(s) will die before googles'.   Other ISP type accounts will come
and go as you change services.

But how do you set your From: separately for every message in the
android mailer - and it seems awkward when you could be connecting
directly to the account in question.

Again, seems awkward to tunnel access to a private host to access
stuff that had just been pulled from publicly reachable accounts.

Android could reply back through the account directly.  Your
complications are coming from combining things in the first place.

Many/most ISP and email hosts allow mobile access with login/password.

Sure, it will work, but I don't really see what you gain over just
using the services as-is as separate accounts, especially if they all
offer IMAP so your computer and phone see the same things.  (Plus your
archived copy if you want...).    I have several accounts myself, but
nearly all of them are configured to forward to gmail and I never use
them directly.

I ran something similar using an SME server as the imap host for a
long time - before google offered imap service.  But now that box is
dead and google is still running...
