Sendmail and Exim will treat 1yz-... as an error.

Not relevant since the scenario we are talking about is not the MUA sending a 150 to the MTA but the MTA sending the 150 to the MUA (so as to restart the Time-Out clock and keep the session Open/Alive).

The only situation where the fact that Sendmail or Exim do not like 150s is valid is when they are RELAYING a message to another SMTP Server that needs to do some extended housekeeping before accepting the message and this is sending interim 150s to say it is working on the request and the session is to be maintained.
