[imp] Return-path problem with IMP on Solaris

[Lisa Koch]

I wrote the following simple wrapper script:
  #!/usr/bin/sh
  echo $@ >> /export/debug/imp.mail
  /usr/lib/sendmail -i -t $@

and saved it as "impwrapper" with owner root, permission 755. 
Substituting this into defaults.php3 solves the problem and correctly
sets the Return-Path:
  $default->path_to_sendmail   = '/usr/thishost/bin/impwrapper'; /*
works */

"impwrapper" logs entries like this (this is what was passed to sendmail
by IMP):
  -i -fuser@coe.neu.edu -- user@coe.neu.edu

But calling sendmail directly fails to set the Return-Path: correctly!
  $default->path_to_sendmail   = '/usr/lib/sendmail -t -i'; /* doesn't
work */

I am mystified!! However, I'm very grateful for the suggestion, as it
(1) helps eliminate possible causes of the problem, and (2) enables us
to get IMP working while we do more detective work.

Thanks to everyone who offered help.  If I figure out something more, I
will let the list know (and I'm still interested if you think you know
why calling sendmail directly causes problems that are fixed by calling
it from a wrapper).

Regards, Lisa
