What is the largest attachment I can send through the Secure eMail Center?
When you initiate a Secure email from the Secure email Center at the interface each attachment is limited to 20mb with total message size limited to 20mb. Remember, although these size restrictions are specific to the Secure eMail (State of Alaska) side of the email equation, the recipient domain may have more restrictive limitations for overall message size and respond with a 552 NDR (Non Delivery Report) in accordance with RFC2821.
