*Encrypt and send email was showing error regarding untrusted sender if the email username contained a trailing space. A trailing space happened once during testing, and occurred when copying and pasting an email address.
*Encrypt and send email now converts newline characters in the email body and subject to CRLF as required by email standards. This bug was causing Direct messages sent from the patient portal to fail, since the body text contained newlines that were not CRLF.
