dovecot - Jun 2014 - list all emails from command line?

This is not strictly Dovecot question, but a more general IMAP one.

I'm running a Dovecot server and have a user who is claiming that some
email sent to him, say, on 30 May, showed up in his mailbox on 02 Jun.

I've checked Postfix logs, and the message was correctly received on 30
May and passed to Dovecot.

A similar issue happens every few days.


This leaves me with two possibilities:

1) Dovecot is somehow not presenting the new mail to the user in a
"timely manner"

2) user's email program is broken


Therefore, I wanted to do some kind of "IMAP list" of the account,
with
a command line tool:

- specify username, pass and server,

- the tool would return a list of all email in their folders (message
  ID, From, To, Date, Subject).


I would run it i.e. daily and this would let me verify when the mail was
really visible in the account.

Is anyone aware of a tool I could use to achieve that?

Hi

I would recommend writing some small check scripts using perl IMAP module. You
can even develop your own monitoring plugins this way.

A different option would be to execute mutt in batch mode on the command line.

This seems like a pretty complicated (and time / labor intensive) way to
solve the problem. That said, if this is the way you want to approach
the problem, Python's imaplib is pretty good at doing this kind of
thing.

This may not format it exactly the way you want, but it should give you
a starting point. Lots of examples online.

I haven't played with it much, but I think there are some things that
will let you do some extended logging of IMAP commands from within
Dovecot - that might be a better way to figure out why the user's client
doesn't seem to be noticing the message in a timely manner.

#!/usr/bin/env python

import email
import imaplib

IMAPHOST='somehost.example.com'
USER='username'
PASSWORD='mysecretgarden'

i = imaplib.IMAP4_SSL(IMAPHOST)
i.login(USER, PASSWORD)
for folder in i.list()[1]:
    folder = folder.split(' "/" ')[1]
    print "**** %s ****" % folder
    i.select(folder)
    typ, [msg_ids] = i.search(None, 'ALL')
    for num in msg_ids.split():
        typ, msg_data = i.fetch(num, '(BODY.PEEK[HEADER])')
        for response_part in msg_data:
            if isinstance(response_part, tuple):
                email_message = email.message_from_string(response_part[1])
                to = email.utils.parseaddr(email_message['to'])
                subject = email_message['Subject']
                msgid = email_message['Message-ID']
                sender = email.utils.parseaddr(email_message['From'])

                print "%-30s => %-30s %-30s (%s)" % (sender[1],
to[1] + ':',
                       subject[0:30], msgid)
