I didn't find it that bad. I used SUSE Enterprise 9, which includes it. 
 From my documentation the only things that I had to work out were:

unixhierarchysep: yes

Otherwise you can't have "."s in the user part of email addresses. With 
the above you can't have "/"s but this is much less common. There 
doesn't seem to be any way to allow both except to use aliasing at the 
MTA level. Our standard for email addresses is "initials.surname at .." so 
we need this.

lmtp_downcase_rcpt: yes

Otherwise addresses are case sensitive and they shouldn't be. I find 
this a strange default;

duplicatesuppression: no

Won't hit most people. If an email arrives with a message ID which is 
the same as one previously sent to the same recipient, it is suppressed 
by default. Message IDs should't be duplicated so it shouldn't matter. 
We have a program which generates emails and generates its own message 
IDs, so when the email is sent the MTA doesn't generate another. The 
problem arises when such an email is resent because the recipient 
accidentally deleted it and wants it back.

I use postfix as the MTA (the SUSE default) and all I had to do to it 
was add the cyrus transport.
