Send mail to multiple recipients with attachment ASP.NET

Question

I am building a simple e-mail application to send emails to a list of people with an attachment.

To be able to add an attachment (from what I have found out) I need to use System.Web.Mail.

Is there any limit to how many email addresses I can send to at once?

Answer 1

Email Protocol should not inherently limit the number of emails sent. Any limits you'll run into will most likely be imposed by your server or ISP.
