Not in the standard smail. However, I happen to have considered this point a

few weeks ago, and I have a patch for smail-3.1.29 that adds a "domains"
attribute to the generic attributes for directors which allows you to do
this.
The patch has been tested by me, but has not been run in a live system.

In conjunction with this it is helpful to have Nigel Metheringham's patch
which
allows a transport to be specified for a smartuser director. (He released
this
for 3.1.28, but I don't know if he has released a 3.1.29 version - I ported
my
own version.) If you have this you can then set up a directors file in the
following style:

# Handle xxx.com

director1: domains="xxx.com",
<whatever>

# Catch unknown names at xxx.com

director2: driver=smartuser, transport=".....",
domains="xxx.com",
<whatever>

# Handle yyy.com

director3: domains="yyy.com",
<whatever>

#Catch unknown names at yyy.com

director4: driver=smartuser, transport=".....",
domains="yyy.com",
<whatever>

# No messages for "xxx.com" or "yyy.com" will ever get this far

director5: director for all remaining domains, without the need
to list them all in "domains"

<further directors for remaining domains>
