gnus fetching same mails again and again (pop)

gnus fetching same mails again and again (pop)

[Yagnesh Raghava Yakkala]

Hello,


I setup a pop mail-source two days ago, 

,----
| (setq 'mail-sources '(pop :server "pop.uni.server"
|                                    :user "me"))
`----

Gnus fetching new mails fine when first enter. but on the group buffer if
press g to see any further new mails, it is fetching the same mails first
again(duplicates). I don't know it's a problem with my server settings or a bug
in gnus.  Now I have 100 unread mails in which 80 of them are duplicates. (I
pressed "g" four times. stupid me).

- how can stop this duplicate fetching?
- is there any way I can delete those duplicates?

My gnus version is from Emacs trunk. (about a week ago.)

Thanks

Check if you have pop3-leave-mail-on-server variable set to other thing
than nil. Otherwise, after fetching the mails, they won't we deleted and
will get downloaded again.

That's it. But how can keep a backup copy on the server similar to
thunderbird.?

Does the mailbox also have an IMAP interface?  That allows more control
over what to do with the fetched mail.

Unfortunately no. Only pop interface. Thunderbird can keep mails on server, is
not it possible with gnus.?

No, Gnus doesn't support leaving the mail on the server.

I use `getmail'.  Using an external tool also gives the
possibility to crontab it.

IIRC, the `pop3-movemail' retrieves the mail from the 1 to the last mail on the
server, that's why get same mails over and over again.

There's no options for Gnus to get from the latest mail, only if totally rewrite
the `pop3-movemail'. ;)

I once wrote a workaround, which calculate local mails' count, and compare with
the server's, and start retrieving from the latest one. It still may mess up, if
delete/copy local mail though. :(

Thanks for sharing the hack., I like your starting comment in your snippet. I
think I will try rely on external tool as XeCycle mentioned.

getmailrc:
--8<---------------cut here---------------start------------->8---
[retriever]
type = SimplePOP3SSLRetriever
server = pop.gmail.com
username = xecycle@gmail.com
port = 995
password = my_password

[destination]
type = MDA_external
path = /usr/bin/procmail

[options]
read_all = False
--8<---------------cut here---------------end--------------->8---

Here I tell getmail to use procmail.

.procmailrc:
--8<---------------cut here---------------start------------->8---
MAILDIR=$HOME/Mail/.incoming
DEFAULT=$MAILDIR/uninteresting/
LOGFILE=$MAILDIR/.procmail.log

:0:
* ^TOxecycle@gmail.com
inbox/
--8<---------------cut here---------------end--------------->8---

Mails not addressed to me are usually list mails, so they go to
uninteresting.  My config is indeed longer than this.  This is
used primarily for desktop notifications, so that it doesn't
inform me of every mail.

--8<---------------cut here---------------start------------->8---
(setq mail-sources '((maildir :path "~/Mail/.incoming/inbox")
                     (maildir :path "~/Mail/.incoming/uninteresting")))
(setq mail-source-delete-incoming t)
--8<---------------cut here---------------end--------------->8---

Then I resplit mail in Gnus to be more specific.

The procmail step is optional.

If you are on a linux or unix machine, you can use fetchmail to deliver
email locally, and then read it in Gnus as local email.  Fetchmail can
be set up to keep email on a POP3 server.

If you can, I suggest you get IMAP access to your account, because
nnimap is working pretty well now.

Re: gnus fetching same mails again and again (pop)

[Yagnesh Raghava Yakkala]

Hello XeCycle,

Thanks for sharing the configuration.  I finally tried getmail. Its working
very well.

It seems getmail stores old mail information in ~/.getmail folder but not on
the server. So the problem is now how to sync the state of getmail between
two computers.

Thanks.,

If you do need this, offlineimap should be a better tool.  I have
only one computer, I didn't use it.

I see offlineimap doesn't work with pop account. After all, I see the best
solution to deal with POP accounts, creating IMAP server.

Hotmail/Uni(pop) -> getmail -> Maildir -> Dovecot -> gnus IMAP.

I couldn't get Dovecot working. Can anyone walk me through dovecot setup.?

Ok.  I'm using debian, which should be very similar.

Ok.  Sounds right.

Note that
 apt-get install dovecot-imapd
is probably enough since it will pull in dovecot-common, and unless you
plan to use POP3 there is no point in pulling it in.

> - edited /etc/dovecot/dovecot.conf

Ok.  I have no setting of mail_location, so I'm using the default, which
appears to be maildir (maildir was the default back in 2008 when I
started using dovecot, and apparently still is).

My changes to the config file, are:
 - enabling imaps
 - using cram-md5 authentication

I've never used shell with dovecot.  I used it back in the day, when I
was using UoW imapd (2001 and earlier).

My definition looks like this:
      '((nnimap "private"
		(nnimap-address "imap.mydomain.com")
                (nnimap-stream ssl))

> - ~/.authinfo (I think this is not the way to do it)

Not anymore, it isn't.  But I'm still using it, and it works for me.

>   ,----
>  | machine localhost login SystemUserid password systemPassword port 143
>   `----

Hm... if you are using shell, and you are using an imapd that can be
started as yourself, you shouldn't need to have the authinfo
information.  What used to happen here is that the imapd is actually
invoked on the shell, and Gnus talks to it using pipes.  Not sure if
this is still the case...?

Also, if the above still holds, the password probably wouldn't be looked
up, since the port number is part of the lookup, and you will not be
talking to the imapd using a port.

Hm... unsuccessful in finding and starting the imapd?  Maybe dovecot
isn't indented to be run in this manner?  Maybe it won't start up
because someone else (dovecot or inetd) are already hugging port 143?

If you do this, instead:
 (add-to-list 'gnus-secondary-select-methods
              '(nnimap "localimap"
                       (nnimap-address "localhost")))

Then it should find your authinfo and connect to whatever's listening on
port 143.

it should not be necessary: if you want to invoke it via nnimap-stream
shell: it doesn't even have to be running. i don't have to start the
dovecot server to use /usr/lib/dovecot/imap.f

i'm using dovecot via shell invocation quite successfully for some time
now. this is what i use as gnus-setup. so basically the same you already
have minus nnimap-address and plus the stderr suppression:


  (add-to-list 'gnus-secondary-select-methods
               '(nnimap "dovecot"
                        (nnimap-stream shell)
                        (nnir-search-engine imap)))
  
  (setq imap-shell-program '("/usr/lib/dovecot/imap 2> /dev/null"))


i don't need any additional authentification. no password, username,
whatsoever.

you might want to try what happens if you invoke /usr/lib/dovecot/imap
in any shell, for me this looks like:

* PREAUTH [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE] Logged in as coroa


i'm using dovecot 2.1.4 on archlinux. i read that for some older
versions you actually want to call it via

/usr/sbin/dovecot --exec-mail imap

instead of /usr/lib/do...


just some random, perhaps helpful information by my side,

have fun,

This is very similar to what I do as well.  I recently switched from
using the whole (Arch) dovecot suit to just invoking the imap program:

#+beginₛrc emacs-lisp
(setq my/imap-method
      `(nnimap "mail"
               (nnimap-stream shell)
               (nnimap-shell-program "MAIL=maildir:$HOME/mail /usr/lib/dovecot/imap")))

(setq gnus-select-method '(nnml ""))

(add-to-list 'gnus-secondary-select-methods my/imap-method)
#+endₛrc

When the facts change, I change my mind. What do you do, sir?

Wow.. That's it. I see localimap is connected.

I am not sure I understand all the terminology or how it is working,
nevertheless it is working. Now I need to configure dovecot to serve all my
Maildir(s) which are fetched by /getmail/.

Thanks.,

That sounds reasonable.

I see similar.

My dovecot version is 2.0.13.

At the end,
gnus *Server* buffer is telling me


  {nnimap:localimap} (denied)

with a warning

Warning: Opening nnimap server on localimap...failed: ; Unable to open server nnimap+localimap due to: Buffer  *nnimap localimap nil  *nntpd** has no process


How can I see why Emacs shell process is denied.?


Thanks.,

Basically it's like this: if you are connecting to the IMAP server that
listens to a TCP/IP port, you will need and use the authentication
information (from the viewpoint of dovecot you are connecting to it from
the internet (even if it is just localhost)).

But if you start the imap daemon as a program and connects its standard
out and in to pipes, and talk to it through the pipes, you don't need
any other authentication, because it's just a program you yourself has
started, reading files under your home directory (ie. owned by you).
