Not necessarily. The recipient list is calculated (and it's in a hashed
order, so it's not alphabetical). In delivery, it is then sorted by
domain and chunked into pieces of size SMTP_MAX_RCPTS (default 500).
Then, a connection is opened to the SMTP server, and the message is
sent in 8 or so transactions of 500 RCPTs each, and the connection is
closed.

The MTA may not like 500 RCPTs per transaction in which case you need
to reduce SMTP_MAX_RCPTS in mm_cfg.py. It may not like a number of
large transactions on a single connection in which case you need to
set SMTP_MAX_SESSIONS_PER_CONNECTION to some non-zero number in
mm_cfg.py. The default setting is zero which means all chunks will be
sent on a single connection. A non-zero setting (1 or 2 or so) means
send that many chunks, then disconnect and reconnect befor sending
that many again until done.
