Here's a discussion of the efficiency of this:
http://www.lifewithqmail.org/lwq.html#multi-rcpt

The claim is that making separate connections is usually faster (fewer
round-trip delays) because of how SMTP works.  It does use more
bandwidth but this is unlikely to be significant on most sites,
most of the time.

These days however, when people send attachments megabytes in size (or
viruses do it for them), I don't know whether that claim is still
true.
