vixie-cron has a run-time dependency on virtual/mta which can be satisfied by 
both exim and ssmtp (and 8 other packages in the tree). ssmtp is the default 
provider.

What has happened is that all versions of exim in the tree that you haven't 
masked have been removed from the tree. I.e. there are no versions in the 
tree below 4.55. Therefore it suggests installing the default provider of 
virtual/mta which is blocked by the version of exim which is still installed 
although not installable (not in the tree). It matters despite the "nomerge" 
because it's a run-time dependency rather than build-time.

You have at least four options. The first option is to upgrade exim and hope 
it'll work. I have no knowledge about exim so I cannot tell you whether it 
will. The second is to restore the ebuild for your installed version in an 
overlay (you can pull it from /var/db/pkg/mail-mta/exim-4.54/) thereby 
restoring a non-masked version of exim.. The third is to add mail-mta/exim to 
package.provided (see `man portage`). The fourth is to unmerge exim and use 
another mta (I'm using postfix).
