Thank you for taking the time to report this bug and helping to make Ubuntu better.
It looks like you are correct. But is there a specific reason this is causing an actual problem for you? Otherwise, it looks like this is extremely low priority to fix.
amavisd-new packaging is derived from Debian. It looks like Debian is also suggesting/recommending packages that don't exist, so this would be best fixed there. Can I suggest that you file an equivalent bug in Debian?
In Ubuntu, I don't expect this to be worked on unless someone makes a case for why it actually impacts users.
