>From your argument it follows (IMHO) that amavisd-new should have no spam
scanners at all because for SpamAssassin there is spamd which could be
easily integrated into your mail system. The same goes for most virus
scanners...

The point of amavis (imho) is that it allows to exclude recipients
from the spam scan or modifying the actions that are taken based on
the result from a spam scan AND each recipient. Without the need to
adapt it for every single server software and spam/virus scanner.
Instead amavisd-new unifies the interface. Why should there be no
DSPAM?

I think DSPAM support in amavisd-new will help. Not only because for
my purposes DSPAM is far better than SpamAssassin but it would help to
diversify the used spam scanners which would make it much harder for
spammers to work on one mail that will get past all scanners.

And after all, no functionality currently present should be removed.
Who likes current system with SpamAssassin only should use it at will.
SpamAssassin will probably even the default scanner for a couple of
years.
