The ebuild currently has LICENSE="as-is" which most likely is wrong. No license is included in the package's tarball. http://search.cpan.org/dist/Mail-Sendmail/ says "License unknown". Can you please ask upstream for clarification under with terms this package can be distributed?
https://metacpan.org/source/MIVKOVIC/Mail-Sendmail-0.79/README#L368 | You can use this module freely. (Someone complained this is too vague. | So, more precisely: do whatever you want with it, but be warned that | terrible things will happen to you if you use it badly, like for sending | spam, or ...?) It was released on CPAN, probably by its author. I don't worry about re-distribution especially when reading above licence statement. Maybe I am too lax.

So I'll commit above snippet as Mail-Sendmail license file and add it to the MISC-FREE group.
Fixed.
