Summary: DoS smtpd vulnerability

Initial Comment:
Method "collect_incoming_data" of "SMTPChannel" class should stop buffering if received lines are too long (possible Denial-of-Service attacks).
Without truncating such buffer a simple malicious script sending extremely long lines without "\r\n" terminator could easily saturate system resources.
