This probably is not a mainframe issue. When I send an email with RCPT TO: <firstname.lastname@example.org> and then put CC: email@example.com after the DATA line, the email shows up in my inbox with firstname.lastname@example.org as the CC. Try it with full address in the RCPT TO: field and the same address without the <> in the CC: line. If the email shows up with a blank CC field, your mail server on the receiving network cannot handle the CC field correctly; you would need to discuss this with the person(s) supporting the mail server you are sending to.
