Small remark. The session log is:

  SMTP>> MAIL FROM:<**DELETED**> SIZE=151847
  SMTP>> RCPT TO:<**DELETED**>
         will write message using CHUNKING
  SMTP>> BDAT 7789
  SMTP<< 250 2.1.0 OK t18si12300997ejj.437 - gsmtp
  SMTP<< 250 2.1.5 OK t18si12300997ejj.437 - gsmtp
  SMTP<< 250 2.0.0 OK t18si12300997ejj.437 - gsmtp
  SMTP>> BDAT 143035 LAST

BDAT sizes are 7789+143035=150824, but MAIL FROM contains SIZE=151847.
They should be equal, isn't it?

And there is no reply from server to BDAT LAST, that is also strange.
Packet capture would be very helpful, yes.
