does qmail+ezmlm divid subscribers in "chunks" by domain?

[???]

for example:
If  I use ezmlm to build a mailling list.
Which has 26 subscribers  :  [EMAIL PROTECTED] -- [EMAIL PROTECTED]
All on the same host "remote.host"

Then I send a message to the mailling list, does qmail+ezmlm
1.Send ONE message to "remote.host". And let the MTA of "remote.host"
deliver the message to
  these 26 accounts?
        or
2.Send 26 message to "remote.host"?


thanks
