Outgoing Mail Server Limitations
For the best service to all of our customers our mail server allows for up to 200 messages to be sent per hour from 1 domain and up to 1000 e-mail messages per day. This limit is set to prevent abuse of the mail server and blacklisting the mail server IP.
If you are planning to send more e-mail per day or per hour than the specified limit then a 3rd party e-mail service may be required.
