Security and ease-of-use are at odds with one-another, so you have to 
sacrifice part of one of those to get the other.  [For instance, this is 
likely one of the considerations of why Debian (at least last I checked) 
didn't have SELinux /active/ by default on new installations.]

For Exim, the one thing I would want to change would be to ship a 
configuration that by default created an SSL certificate and enabled 
MAIN_TLS_ENABLE to enable TLS SMTP transfers.  [The Postfix package in Debian 
does this.]  There's documentation and help for doing this for Exim in 
/usr/share/doc/exim4-base/README.Debian.gz in Section 2.2 though, and so I 
suspect there's a _reason_ why this isn't the default.

I think the negative point of "Support community limited outside of Debian" is 
untrue.  The exim-us...@exim.org mailing list is very active and responsive, 
and Exim has become the most popular MTA since sometime in 2008.
