JavaMail : Limitations on the count for sending mails

问题

Limitations on the count for sending emails using JavaMail

1. What is the maximum number of emails can be present in the to/cc/bcc list?
2. What is the maximum number of emails that can be sent in a Session?

Does these numbers depend on the SMTP server configuration?

回答1:

All of those numbers depend on the server. JavaMail imposes no limits other than available memory.
