Or even, as with one of my customers, an upgrade from MS Small Biz server 2003 to
SBS 2011 ... and I was asked to let the new Exchange use exim as for outgoing
mail -- MS exchange just did not seem to work (I didn't ask why).
They would have liked to move away from a MS server (which only does MS Exchange
& LDAP) - but they are wedded to Outlook on the desktop. There (still) is not a
true open source 'drop in' MS Exchange replacement ... close, but not quite
there. Zarafa keep the 'outlook connector' bit proprietary.
Shame. If anyone has 'spare' time, work here would be really good. Part of the
problem is that what people expect by ''email'' is (from the Unix users'
perspective) several different things: sending mail (exim), retrieving email
(imap), groupware (calendaring mainly).
