Is bad From_ line an error by procmail, sendmail, or neither?

1999-09-28 11:59:48
I received an ugly spam in my junk folder which caused elm to fall
over thinking the folder was corrupted. (Pine reads it fine, btw.) The
problem is that the sender name in the From_ line has a leading, but
no trailing, double quote. At least I assume that that is the problem,
since adding a second double quote fixes the problem. I suspect that the
problem is with Netcom/Mindspring/Earthlink's sendmail, but want to be
sure that it isn't procmail.

"|TZ=EST5EDT; export TZ && exec /usr/local/nuglops/bin/procmail -tf- MODE=prod 
|| exit 75"

My .forward file, shown above, directs procmail to rewrite the date
stamp on the from line, and should not be changing the sender name, as I
read the following:

     -f fromwhom
          Causes procmail to regenerate the leading `From '  line
          with  fromwhom  as  the sender (instead of -f one could
          use the alternate and obsolete -r).  If  fromwhom  con-
          sists  merely  of a single `-', then procmail will only
          update the timestamp on the `From ' line  (if  present,
          if not, it will generate a new one).

The question is, might procmail rewrite the whole From_ line given the
above invocation and the message quoted below? Another possibility is
that the process which does the MIME Autoconversion caused the problem.
Comments? Answers?
