Limit to #of emails sent?

I just set up a new Dreamhost email account and configured Outlook to use it when sending email. The testing worked fine. Then I used it to email a large number of people in the neighborhood. I emailed the first batch of 80, cc’ing myself, and it appeared to work, at least I got the message. The 2-6 batches of 80 gave me no feedback.

Is there a limit?


Thank you LakeRat! Guess it will take 6 hours to send an email
