Email error: 554.7.1

I have been successfully using the email client for a year as my primary email. All of a sudden, in conjunction with a modest increase in outgoing email volume, I cannot send mail. Every time I hit send, I instead get this error message: “554 5.7.1 Data Command Rejected: maximum recipients exceeded for davidoyer, please contact support.” Has anyone else experienced this?
