I am having trouble with the first y command.  Note that I have changed the list name and list server as this should fit any mailing list that uses DKIM, from what I see in your script itself:

bash# echo 'From: "Sender Name [email protected]" <[email protected]>' | sed -f fix-dkim-from.sed
sed: file fix-dkim-from.sed line 61: strings for `y' command are different lengths
bash# grep -w y fix-dkim-from.sed
  y/    / /
  y/\n/ /
bash# 
 
Any idea what I am doing wrong, or what is wrong with my copy of the script?  I just quoted the From line above as an example, I get the same error message when I do:

cat email/filename | sed -f fix.dkim-from.sed

I did have trouble navigating bitbucket, and ended up printing a copy of the html page.

Then I went back and got the gzip version of the script, and when I run that as above, there is no error, but I get no output, whether I just echo the From line, or process the whole email.  Is that because the first line of the script is:

#!/usr/bin/sed -nf

When I remove the -nf, I still get no output??  As in, the script runs quietly and all I see as the result is a bash prompt.

Thanks,
