I am stuck in my SSH telnet session, trying to test an SMTP connection, but when I enter a period to submit the data of a test email - nothing happens. I can end the session with the control] - but I want to submit the data, not close the session. What am I missing?
Ubuntu 16.04 Client. Debian 8 server. Qmail.

rcpt to: <nospam@test.com>
mail from: <testmail@test.com>

rcpt to: <nospam@test.com>

Subject: Just a stupid SMTP test
Just a test !
\r\n503 MAIL first (#5.5.1)<return linefeed doesn't do anything either)
