  399. NOTES FOR SENDMAIL
  400. ==================
  401. Sendmail is not passing the envelope sender (also known as the value of header
  402. "Return-Path") to the executable. Although it won't be a fatal error, the header
  403. should be checked to detect bounces more easily.
  404. In order to let sendmail pass the header, you need to modify your sendmail config
  405. (sendmail.cf) and add the char "P" to the field "F" in line "prog".
  406. e.g from:
  407.   Mprog,   P=/usr/sbin/smrsh, F=lsDFMoqeu9, S=EnvFromL/HdrFromL, ....
  408. to
  409.   Mprog,   P=/usr/sbin/smrsh, F=lsDFMoqeu9P, S=EnvFromL/HdrFromL, ....
  410. "P" should already be defined as "HP?Return-Path: <$g>" (in sendmail.cf too).
  411. Don't forget to restart sendmail afterwards.
