Wrong receiver address displayed

Pozzo-Balbi

Hi,

a Webapp plugin does not solve the problem. Emails synced via z-push still have wrong email, same goes for IMAP sync. Further the “sed -i” of kopano-dagent also works on attached emails (sic!). See picture

See post https://forums.zarafa.com/showthread.php?13528-Zarafa-Kopano-replace-alias-emails-with-email-of-user&p=58359&viewfull=1#post58359 for full problem explanation.
Last but not least, to prove that it is a bug and not a feature, I have use of GAB disabled where possible (e.g. server.cfg: enable_gab = no). I use ldap plugin.

A kopano-dagent setting to disable this behaviour would be greatly appreciated.

Thanks

Yeah, I just noticed that the problem still appears on mobile/zpush. I’m probably just going to patch this out of dagent myself, and put it behind a config option. I can submit a patch/pull request to the kopano source tree if you guys take code?

Sure, patches are welcome! You can find the contributing information at https://stash.kopano.io/projects/KC/repos/kopanocore/browse/CONTRIBUTING.md and as long as you make this behavior optional and non-default I don’t see a problem with it.

OK, I’m working on a patch but it’s a little harder than I thought. It seems there’s no explicit point in the code where this happens. I was looking in ResolveUsers() but I don’t think that’s it.

I actually ended up writing a DAgent plugin for this. This was way easier and a little easier for me to manage with regards to upgrades. It’d be nice if there were srpms for the open source packages :)

This does only partially fix the problem though: From headers are still rewritten which is very confusing too :)

Maybe this shows what my/our problem is though. I don’t know how much work it’d be to do this in DAgent directly.

import MAPI
import email
from email.utils import getaddresses

from MAPI.Util import *
from plugintemplates import *

class RewriteUsers(IMapiDAgentPlugin):

    def __init__(self, logger):
        IMapiDAgentPlugin.__init__(self, logger)

    def PreDelivery(self, session, addrbook, store, folder, message):
        headers = message.GetProps([PR_TRANSPORT_MESSAGE_HEADERS], 0)[0].Value
        msg = email.message_from_string(headers)
        to_addrs = getaddresses(msg.get_all('to', []))
        cc_addrs = getaddresses(msg.get_all('cc', []))

        names = []
        for addr in to_addrs:
            names.append([
                SPropValue(PR_RECIPIENT_TYPE, MAPI_TO),
                SPropValue(PR_DISPLAY_NAME_W, unicode(addr[0])),
                SPropValue(PR_ADDRTYPE, 'SMTP'),
                SPropValue(PR_EMAIL_ADDRESS, unicode(addr[1])),
            ])

        for addr in cc_addrs:
            names.append([
                SPropValue(PR_RECIPIENT_TYPE, MAPI_CC),
                SPropValue(PR_DISPLAY_NAME_W, unicode(addr[0])),
                SPropValue(PR_ADDRTYPE, 'SMTP'),
                SPropValue(PR_EMAIL_ADDRESS, unicode(addr[1])),
            ])

        message.ModifyRecipients(0, names)
        return MP_CONTINUE,

@hpvb thanks for posting the plugin. If you add some documentation and add upload it somewhere (be for example in a gist at Github), then you could also add it to https://stash.z-hub.io/projects/COM/repos/projects-and-resources/browse#Kopano-dAgent-Spooler-Plugins

hpvb

@fbartels sure, I’ll setup a repository for it and add some documentation. This may be useful for others besides just me and the other two people in this thread.

fbartels

@hpvb great. if you need any assistance let me know. If you don’t want to create a Github/Whatever account, then you could also create a personal git repo on stash.z-hub.io.

hpvb

@fbartels Does this look OK to you?
https://notabug.org/hp/kopano-dagent-rewritegaladdresses

If so I’ll add it to that wiki page.

fbartels

@hpvb did not test your script, but the description reads fine for me. Thanks for making a repository for it.

hpvb

I’ve sent a PR for that repository. Thanks for your feedback.

Pozzo-Balbi

@hpvb thanks a lot. Can’t wait for your patch to reach nightly builds.

hpvb

@Pozzo-Balbi I didn’t end up writing a patch for dagent, but a plugin for dagent. You can get it here : https://notabug.org/hp/kopano-dagent-rewritegaladdresses. Once that is installed everything should start working. I’ve had it running for 5 days now without issue.

Can someone please fix the Plugin. It´s not working with Python 3 in Kopano 8.7

Thanks
