What is the limit of sending daily e-mails with “mail()” php function?

I have the shared dreamhost plan.

Can I execute a php script to send 100.000 e-mails using my shared reamhost plan?

Thank u.

No, not even close. (The limit is 100 emails per hour.) If you need to send that many emails, you will need to set up an account with a bulk email provider.
