I haven't tracked this thread, but here are some suggestions.  Please note that
I've never had the need to install multiple MTA's.

1. emerge -pv qmail - on my system this gets
[ebuild  N    ] sys-apps/ucspi-tcp-0.88-r5  +ssl -ipv6 
[ebuild  N    ] net-mail/dot-forward-0.71-r1  
[ebuild  N    ] net-mail/checkpassword-0.90-r1  
[ebuild  N    ] net-mail/cmd5checkpw-0.22  
[ebuild  N    ] sys-apps/daemontools-0.76-r3  
[blocks B     ] net-mail/ssmtp ("virtual/mta" from pkg net-mail/qmail-1.03-r10)
[ebuild  N    ] net-mail/qmail-1.03-r10  +ssl 

All of the lines except 'B' are prereqs that would be installed.  Also, qmail
will be installed with USE="+ssl" to allow ssl use.

The 'B' is because the package net-mail/ssmtp is already installed and
registered as the "virtual (see "/usr/portage/profiles/<profilename>/virtuals)
that provides mta support, so I would need to do the following.

2. emerge -C ssmtp - remove the blocking package.
   emerge qmail

3. For more information, search on the gentoo forums or ask your question on the
IRC channel http://www.freenode.org/ #gentoo.

HTH,
