Like I said before, I dont agree with that point of view at all - Cyrus 
is an excellent imapd that scales very well, from 3 user systems to 
45,000 user systems ( the largest that I've seen, there are most likely 
larger setup's out there ).

There is an old Indian saying : things you know about tend to be easy - 
things you have no clue about, tend to be really hard.

When such arguments are raised, I find it has great significance, since 
it explains the entire argument over. So if you comfort zone is Courier, 
so be it, nothing wrong with that, use Courier - its a good email 
solution - but dont slag off Cyrus because of your mindset.

You dont need to rebuild anything in order to get cyrus-imapd working 
with mysql, it works out of the box as supplied within CentOS4. Again, a 
point that emphasis your knowledge pool lies elsewhere.

Incorrect again. Its actually courier that you are going to need to 
rebuild from source, maintain and test yourself ( which includes 
tracking security fix's and vuln's over the Internet, rebuilding and 
testing on your own each time there is a fix etc, and if that fix 
involves a version update that breaks configs.... foobar! ). I think you 
missed my point about app acquisition + maint from the last email.

Also,  we're drifting off here, Morten ( the OP ) wanted to know what 
imapd to use with the distro, Since Dovecot and Cyrus are included 
within the distro, my recommendation is going to be -> use one of them. 
Dovecot works out of the box, cyrus needs a couple of lines edited.
