It's of course not a production code. I'm only trying to
learn and understand how exactly it works.
I cannot find anything about "--" in the postfix documentation
(or I'm looking on the wrong page?). There is any explanation
somewhere? (instead of at the source code).
Thanks for your help!

I use dovecot-lda for delivery where the parms are:
-d ${user}@${domain} -a {recipient} -f ${sender} -m ${extension}
Perhaps they may work for /usr/libexec/dovecot/deliver
[0:root@elmo webmaster]$ rpm -q dovecot

I think I can do the same in Ruby using IO.popen like:
IO.popen(["/usr/sbin/sendmail", "-G", "-i", my_str], "w") do |pipe|
as I see in this case I don't even need to use my_str with \" \".
But I'm still confused about -f option in master.cf, and characters "--"
between ${sender} and ${recipien

Sorry, that is still a shell command line. You need an API that

Good point. I changed it to:
IO.popen("/usr/sbin/sendmail -G -i \"#{my_str}\"", "w") do |pipe|
So now it should be secure (same as using $@ instead of $*).

And there you have a giant security hole. What happens if an email
address contains shell special characters? You specify flags=Rq in
the pipe daemon command, but that quotes email addresses according
to RFC822, not to
Hi All,
I'm trying to understand how content_filter works. According to the
documentation I can create a simple script and use content_filter to send
an e-mail to it.
That's my config of master.cf:
