smtp limit

I am sending out a newsletter via a contact form on our site and I was wondering would it be better server wise to send it out once with every email listed as bcc or would it be better to send them out individually and if I send them out individually is there any kind of limit to how many I can send an hour or so
I need to send 2000 of them

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hi,

This is depend on the Mail server.

THe normal mail server allow 25 mails at a time and 10 mails in 3 minute
so its depend on the mail server and hosting company policy
