Just make an alias entry with:
aliasname: :include:/path/to/file

and run newaliases.  Then you can edit the file any time to change that 
list.  I sometimes give the files .txt extensions and put them somewhere 
with samba access so others can edit with windows/notepad.  Sendmail 
doesn't seem to care about the line endings - just make sure it has read 
access permission.  Also, if you didn't already know, aliases can 
include other aliases and sendmail will recurse until things stop 
expanding, weeding out any duplicates so if you have a common group with 
a few others you can put the common group in one list, then mention its 
alias in the others along with their unique entries.
