E-mail newsletters - how to control send?

Hi folks,

I have a site that ends out e-mail newsletters - currently to around
900 subscribers.

Is there an easy way to control the actual *send* to the mail server
so all 900 don't hit it at once?

Do multiple sends (from the same sender) tend to trigger spam
controls on mail servers?

My first thought was adding timing loops between batches, but then the
whole page would reach the php.ini timeout before finishing, would it
not?

Presently, the newsletter functions are part of an admin back-end -
I'd rather add some decent routines than foist a stand-alone email
sender application on ther poor client.

TIA,

Adam.
