No, I know several ISP's using "exim" as MTA and "courier" as IMAP. My ISP <http://www.freenet.de/> has around 5 million E-Mails hosted and now run over 90 mbox-Servers which mean, arround 55.000 mailboxes per Server. Since you can have a free email (20 MB storage), and two commercial accounts (2.5 GByte as me, or unlimited :-)) ) you can calculate a bit. My own account <linux4michelle> hold currently ober 120.000 messages and I use it as backup for my very importand messages @home. I run for the french GOV the Courier-Suite (MTA+IMAP) with over 17.000 users where some user have over 2 million messages in there account... My own Courier @home holds currently 7.43 million messages since I have a very long mailinglist history... (over 180 Mailinglists and 11 years). I found that "courier" handel this times better then "cyrus" or others. And for the filesystem I use sucessfuly since over 5 years "ext3" because "reiserfs" had and has real problems with 500.000.000 inodes (a hale Miliarde) per Raid-5 (I have currently 3) even it claims to be better then ext3.
