Two possibilities I can think of:
First, can Amanda write the dumpdates on the client? If not, every incremental
will end up a a full, since it will all be 'new'.
Second, if your /Mail directory contains email, depending on the mailbox format
there may be no way to do an incremental.  For example, an Exchange sever puts
it all in one big database, so it is all new every day. The original unix 
format,
where each user's email is just appended to a file named for the user, will also
appear as all new daily.  If, however, your mail program keeps each message as
an individual file then you should be able to have incremental's smaller than 
your
full.
  There are debug files on the client (possibly in /tmp/amanda) that should
show what size was estimated for the current level and from the next higher
level.  Does it report the same size for both?

One other thing, do you use the same location for dumpdates for both configs?
