Following the plans from yesterday, I finally  made  the  mailing
list  for  mmh  ready  to be used. Also registered it on Gmane. I
didn't write a welcome message yet, because I want to wait  until
Gmane does archive the list.


I have two PGP keys in active use: An old 1024D key and  a  newer
4096R  key.  Both  are well integrated into the web of trust. The
weaker key is the one I use for everyday work:  signing  and  en-
crypting  email, signing software packages. The stronger key does
only reside on hardware I control. I use it for signing  software
packages  as  well,  but  much  less  for email, because it's not
available on the server where I do my emailing.

If I receive encrypted mail from others, they  usually  encrypted
with  my  stronger  key  -- that's understandable, of course. But
this makes it more difficult for me: I need to copy  the  message
on  a  self-controlled  machine, decrypt it, then copy it back to
the mail server. To ease this task, I wrote a script today:

     #!/bin/sh
     #
     # fetch remote messages, decrypt them locally, then push
     # the cleartext versions back to the remote machine
     #
     # depends on: ssh, mmh

     sshcmd='ssh -p1234 user@example.org'

     temp="`mktemp -d`"
     trap 'rm -rf "$temp"' 0 1 2 15
     export MMH="$temp"
     echo "Path: $temp" >"$temp/profile"

     $sshcmd MMHC=/dev/null packf "${@:-c}" >"$temp/mbox"
     inc -file "$temp/mbox"
     mark -seq orig a
     for i in `scan -form '=%(msg)'` ; do
             mhpgp -w "$i"
     done
     for i in `scan -form '=%(msg)' !orig` ; do
             <`mhpath "$i"` $sshcmd MMHC=/dev/null rcvstore
     done
     # if inc(1) could read from stdin, then we could use
     # `packf !orig | $sshcmd inc' instead of the second loop.
