Yes, but if there are many recipients on the one message then there is
no reason to send many parallel streams to the final server.  The
system can send one stream with all of the recipients, rather then
many identical streams with a couple of recipients each.

It also depends on strongly on which MTA you are using.  I am very
familiar with the Windows 2000 SMTP Server, and not as familiar with
sendmail or postfix (I've used them for many years, but I haven't dug
into them).
