Hi Dan,
You need to take into account important things like:
1 - Clients don't really care if you use open source or monolithic
standars, they only need to know if it works well in a long term and also
the price;
2 - In my case I have hundreds of domains with about 05 email accounts per
domain. So I need to minimize technical support and offer standarized and
practical solutions.
3 - Moving to MS Exchange is not a practical thing to do for many reasons,
price is the first problem.
4 - Google Apps and office 365 are very attractive solutions for mail
hosting and users seam to like it.
So basically as a service provider I need to offer complete solutions.
Sogo, if it works with qmail, will enable qmail servers to offer many more
funcionalities, since is sits in the middle between open source mail
servers and MS Exchange. Please to go http://www.sogo.nu/about/overview.html

Hi,
I only do backup once a week :( and the backups are local to another NAS
As for the IMAP I must agreed that it's safer since they benefit from the
backups of the server.
But there is a downside: As time goes on the user will have a larger
Inbox/Outbox folder and that means loading those folders every time the
user logins. You need to have a fast WAN connection to keep many clients
using IMAP :(
IMAP is good when client and server are very close, like the squirrelmail
and the courier you have on your qmailtoaster, that works perfectly. ut
when you separate IMAP client from the server, things are not so good.
That's why I am investigating the MAPI protocol as an alternative to
deploy for my clients and also to fight the growing need to Office 365
which comes with MS Exchange online.
Sogo is an alternative to MS Exchange and it's believed to work with
qmailtoaster. But I never had time to test it.
Why don't you try it?
You raise valid concerns regarding mailbox size... however, by teaching
your clients to create and use both online and offline folders, you
considerably mitigate those issues... for example, I have several Insurance
Agencies as clients -- they routinely get about 4GB of emails per year on
their main site... but by separating them as they come in into existing,
new, old clients; and then in to auto, health, life, and other folders,
the sizes become VERY manageable. Then, once every 6-months, we archive
everything more than 18months old into offline storage. Thus, they can
search (nearly instantly) the last 18 months of emails, and can search
(locally, and more slowly) older messages very easily.
Most of these clients use Thunderbird and IMAP... there are known issues
with Outlook (esp. 2003 and older) and IMAP... if you ask me, issues
PLANTED by MS to encourage using Exchange vs. IMAP...
As for using MAPI, my only concern there is that I prefer to stay away
from monolithic standards (that is, standards that are controlled by a
for-profit company)... and Microsoft has a well-earned reputation (think
Active Directory) for making unilateral and unannounced changes to their
standards specifically to break compatible 3rd party applications. (In
Microsoft's defense, they do have a more recent history of working WITH the
Open Source community... but its going to take more of a track record for
me to trust MS standards... and I'm not there yet.
Of course, one of the best things about Open Source is that we all get to
do our own thing for our own reasons!
