That's how we do it.  We run mirrored surgemail for the HW redundancy and only give public access to the one. 

And I switch the two servers periodically to be sure things are working nicely.  The mirroring is much better than it used to be..  After a switch, there are  few cases of customers wondering why a email they deleted months ago has suddenly reappeared as new.  It prevented 2am switchovers because people's blackberries would throw an alert when email shows up.

I'm testing doing backups of the user email from the filesystem on the non-public mirror, as the main server gets io-burdened to have an rsync running during mail delivery.  I don't want to be responsible for customer content.  I hate it.  But so many users simply don't know.  They call asking why they're always at quota, even after they delete email (gotta empty the trash, man!) and with gmail giving what, 11GIG?  Ridiculous!

In my old day job we just used to run a mirrored server, surgemail pricing is fantastic for that. If a user deletes their own email then that's there fault but if we lost a server we still had the mirror. Works a treat.

We offer accounts with unlimited quota and have several clients who use more than 50 GB in one account. Which is great, as we charge for storage in increments at a suitable multiple of Amazon S3 rates.

A number of clilents came to us specifically because they were unable to purchase additional quota from their existing provider at any price, or their in-house Exchange Small Business Server exploded, and their IT provider quoted them a system upgrade in five figures.

YMMV.

We also offer webmail access.  As a result, there's an implication the onus is on us to preserve their email.  Increasing the quota will just give users more room to keep email on our server that they should be saving locally.
