A mail with 100 recipients to the same domain is sent iirc as one mail to the target server and there it is split up into 100 mails.
Otherwise maybe this old thread helps you:

Sending messages with a limited number of recipients:
- max_rcpt option on smtp transport.

Getting a delay of a second between them? Hard.
Don't try unless you really really need to.


Mind, no reasonable remote server should run into
trouble with such. At worst the should temp-reject
any recipients offered after their limit is reached,
upon which splitting has been done automatically.
We will try the remainder later.
