That will not work.

You'll get a warning message

  $ grep testme /etc/aliases
  testme: user1
  testme: user2
  $ newaliases
  /etc/aliases: line 105: testme... Warning: duplicate alias name testme
  /etc/aliases: 80 aliases, longest 10 bytes, 812 bytes total

I think the second entry will get the mail; aliases are stored as db
or dbm files, and so only have one value per key.  Sendmail doesn't
merge keys.  (At least looking at the resulting DB file I only see
"user2" in the file).

That is the correct format.  Use it :-)
