Is there an E-Mail client for linux which allows to search old gpg encrypted mails (i.e. find all mails which contain a particular keyword in the body, including the encrypted ones).

I just saw the other response and guess I never wrote up the solution I actually implemented. It turns out that python imaplib is straightforward and I wrote a very quick script. Barring a few changes (e.g., anonymizing my various USERNAMEs, EMAILPASSWORD, WORKDOMAINNAME, MYGPGKEYID). I also don't just send encrypted it; but prepend the subject with the username of the sender and put some of the header stuff before the GPG (in case I'm reading it on my phone and can't decrypt).
#!/usr/bin/python
import imaplib
import email
from datetime import datetime,timedelta
import shelve
from subprocess import Popen, PIPE
def piped_call(command1, arg1_list, command2, arg2_list):
"""
if arg1_tuple = (a10, a11, a12); arg2_tuple is (a20, a21)
This executes "command1 a10 a11 a12 | command2 a20 a21 a22"
"""
if type(arg1_list) not in (list, tuple):
arg1_list = [arg1_list,]
if type(arg2_list) not in (list, tuple):
arg2_list = [arg2_list,]
p1 = Popen([command1,]+list(arg1_list), stdout=PIPE)
p2 = Popen([command2,]+list(arg2_list), stdin=p1.stdout, stdout=PIPE)
p1.stdout.close()
return p2.communicate()[0]
shlf = shelve.open('/home/USERNAME/mail/mail.shlf')
# This shelf (a persistent python dictionary written to file) has as its key
# the IMAP message ids of all emails that have been processed by this script.
# Every time the script runs, I fetch all emails from the current day
# (except from midnight to 1am, where I fetch all emails since yesterday)
# and then send all emails that haven't been sent previously
# by checking message ids against the python shelf.
M = imaplib.IMAP4_SSL(host='imap.WORKDOMAINNAME.com', port=993)
M.login('EMAILUSERNAME', 'EMAILPASSWORD')
M.select()
dt = datetime.now() - timedelta(0,5*60*60)
# Only search for messages since the day of an hour earlier.
# This way messages from yesterday don't get lost at midnight; as well as limiting the number of messages to process through to just todays.
typ, uid_data = M.uid('search', None, '(SINCE %s)' % dt.strftime('%d-%b-%Y'))
for num in uid_data[0].split():
typ, data = M.uid('fetch', num, '(RFC822)')
e = email.message_from_string(data[0][1])
print 'Message %s\n%s\n' % (num, e['subject'])
if num not in shlf:
sender_email = e['return-path']
for s in ('<', '>', '@WORKDOMAINNAME.com'):
sender_email = sender_email.replace(s,'')
subject = "%s: %s" % (sender_email, e['Subject'])
body = ("From: %s\n"
"To: %s\n"
"Cc: %s\n"
"Subject: %s\n\n" % (e['From'], e['To'], e['Cc'], e['subject']))
payload = e.get_payload()
if type(payload) in (list, tuple):
payload = str(payload[0])
else:
payload = str(payload)
encrypted_payload = piped_call('echo', (payload,),
'gpg', ('-e', '-a', '-r', 'MYGPGKEYID'))
body += encrypted_payload
piped_call('echo', (body,),
'mail', ['USERNAME@gmail.com', '-s', subject])
shlf[num] = datetime.now()
M.close()
M.logout()
I then added the following lines to my crontab (the script above is named mail.py inside a directory called mail), so it will run every 5 minutes during the normal hours on weekdays (M-F 8-7pm) and less frequently at other hours. (crontab -e)
# Every 5 minutes, M-F from 8am - 7pm.
*/5 8-19 * * 1-5 cd /home/USERNAME/mail && ./mail.py >> /home/USERNAME/mail/mail.log 2>&1
# Every 30 minutes, Sat&Sun from 8am-7pm
0,30 8-19 * * 6,7 cd /home/USERNAME/mail && ./mail.py >> /home/USERNAME/mail/mail.log 2>&1
# Every 30 minutes, M-F 8pm-2am; (no emails 2am-8am)

Traditional mailx does not support IMAP or POP, but the one that comes with Linux does.
For your particular problem, I recommend using fetchmail
instead. You can use the --mda
option to have fetchmail
execute a script of your choice for each downloaded message. It can even pass the From and To addresses as parameters to your script if you use %F
and %T
as placeholders in the command line.
First, create a mailsorter
script:
#!/bin/sh
dest_mbox="$1"
from="$2"
to="$3"
case "$from-$to" in
someone@example.net-myname)
echo "From $from `date`" >> "$dest_mbox"
cat >> "$dest_mbox"
;;
*)
cat > /dev/null
;;
esac
Then run fetchmail -u myname popserver.example.com --mda './mailsorter /tmp/mbox %F %T'
While testing this solution, give fetchmail
the --all
and --keep
flags to make sure that you don't delete your mail accidentally.

Mutt has pretty good PGP integration. The wiki shows what settings you need to add to your
.muttrc
; these settings may already be present in the system-wide configuration file (for example, on Debian, PGP/gpg works out of the box).Mutt supports mbox, mh and maildir mailboxes. If you search in a mailbox that happens to contain encrypted mail, you'll be prompted for your gpg passphrase (if you haven't already entered it in this session either in mutt or in an external keyring program), and mutt will find occurrences in encrypted mails.
Mutt doesn't have a command to search multiple mailboxes. If your mails are stored in single files, you can make symbolic links inside a single directory to make a huge mh-format mailbox; it may be a little slow.
Also, I haven't used it, but Notmuch is a recent tool to manage email that supports gpg and is good at indexing, so it should support searches of encrypted mails.
