How can I extract mail with attachements without having to use pine or a Netscape mailer?


On Unix use the CMU programs "mpack" and "munpack". (Look here for a solution with "metasend" and "metamail"). For mpack on Macintosh, look here .
An example how Alice (alice) writes to Bob (bob.org) and sends him a jpg file photo.jpg.


mpack -s "photo for you" photo.jpg bob.org
Bob (bob.org) unpacks the file by saving Alice's email first in a file "fromalice.tmp" and then uses the command:

munpack fromalice.tmp

to unpack it.


How do I configure Netscape so that it opens a PDF,DVI or PS viewer automatically under Linux or Solaris?

Check the entries in the three files ~/.netcape/preferences.js , ~/.mailcap and ~/mime-types . In ".netcape/preferences.js" you should have among other entries
user_pref("helpers.private_mailcap_file", "~/.mailcap");
user_pref("helpers.private_mime_types_file", "~/.mime.types");

user_pref("mime.table.extension.ps.outgoing_default_typ",  "application/x-ps");
user_pref("mime.table.extension.pdf.outgoing_default_typ", "application/pdf");
user_pref("mime.table.extension.dvi.outgoing_default_typ", "application/x-dvi");
in ".mailcap", there should be
application/x-dvi;xdvi %s 
application/pdf;gv %s
application/x-ps;gv %s
in ".mime.types", there should be
type=application/x-ps   desc="Postscript Document"        exts="ai,eps,ps"
type=application/pdf  desc="Portable Document Format"   exts="pdf" 
type=application/x-dvi  desc="TeX Dvi file"               exts="dvi"
