Title: Advice, Imap and email box sizes.
Post by: Drifting on January 17, 2013, 06:44:31 PM

Hi All, advice needed please.

A close friend has a small business, and up till now has used MS Small Business Server 2003. Sadly the hardware he is running is on it's last legs, and he cannot justify the hardware cost for going to SBS 2011. So was considering SME for them.

His problem is that they run a home business which has a very large mailbox sizes. both the users refer back to email over a few years. Exchange has coped with their mailboxes reaching 7-10GB each (Yeah I know :-( ) But how would iMap cope with this?

Regards Paul.

Thankyou.

Server I have in mind will have 32GB ram, so things should fly.

I would add that Thunderbird or Apple Mail do a terrific job with large imap mailboxes -- much better on both my SME and Kerio mailservers than Outlook.

Thanks for that, sadly they are stick with outlook as this links in to another third party product. After the speed this thing was working under exchange, I imagine anything would be quicker on the backend.

I *think* the (my) problem with outlook is that it off-loads searching and indexing to the exchange server.  Consequently, with a good exchange server outlook works great.

With a fake exchange server (Kerio) or a simple IMAP server (SME), I find that if I start an email search in Outlook I can open Thunderbird, let it download the last week's worth of email, search, and find an obscure email from 6 years ago before Outlook finishes.

Keep in mind Outlook's PST file size limit.
