Ok. Well, every email client I've ever heard of has used comma-delimited

During the actual SMTP transaction, each email address is handled
separately. The client will send each email address as a separate "RCPT"
command to the message submission server. And the relay agent, which
forwards the email from Hotmail to the destination, will open one SMTP
transaction per email address (aka "RCPT") per domain gateway (MX) server.
Which is why one email to ten recipients is the same as ten emails to one
recipient each; i.e., ten messages.
