Cannot forward email with fetchmail to Kopano for one user



  • Hi all,

    Yesterday I updated my old Zarafa server to Kopano 8.6 on Ubuntu 16.04. The majority works fine but for one user I am not able to fetch emails using fetchmail. I think it is problem is with Kopano (however I am not sure). In the server.log I find the following entry:

    Sat Jul  7 17:16:19 2018: [warning] Authentication by plugin failed for user "omega": Trying to authenticate failed: wrong username or password
    

    Fetchmail reports the following:

    Sun Jul  8 08:03:54 2018: [17945] [error  ] HrLogon server "default:" user "SYSTEM": logon failed
    Sun Jul  8 08:03:54 2018: [17945] [error  ] HrLogon server "default:" user "omega": logon failed
    Sun Jul  8 08:03:54 2018: [17945] [error  ] Access denied or connection failed for user "omega", using socket: "default:": logon failed (80040111)
    Sun Jul  8 08:03:54 2018: [17945] [error  ] HRESULT deliver_recipient(pym_plugin_intf*, const char*, bool, FILE*, DeliveryArgs*): HrGetSession failed: logon failed (80040111)
    Sun Jul  8 08:03:54 2018: [17945] [error  ] int main(int, char**): deliver_recipient failed: logon failed (80040111)
    fetchmail: MDA returned nonzero status 70
    fetchmail:  not flushed
    

    Of course I checked the passwords and the overall configuration - but since I am using the same method for another user, the configuration in general should be okay. I can login to the webapp for this use. In the .fetchmailrc I instruct Fetchmail to forward the fetched messages:

    mda "/usr/sbin/kopano-dagent omega"
    

    I am really confused (and also frustrated), so any help would be highly appreciated.


  • Kopano

    In which user context are you running fetchmail? To be able to deliver mails the local user needs to have admin permissions (local_admin_users in server.cfg) in Kopano (that actually was the same in Zarafa).



  • Hi,
    thanks. I am using Fechtmail exactly as suggested by you: I want to fetch messages from another server (to which I also have access, no error there) and deliver them to Kopano users.

    Anyway: You posted the solution! However, I am quite surprised that it worked for the other user…

    Thank you!!!



  • Hi,
    I have a follow-up question: Thanks to fbartels the fetching of mails works. In fact, I am not aware about any problems anymore. However, once in a while I still find the following entry in the registry:

    [warning] Authentication by plugin failed for user "omega": Trying to authenticate failed: wrong username or password
    [warning] Previous message logged 64 times
    

    What does this mean? It would already help me to understand, to which plugin the entry is referring to. I did not install any plugins so it must be from kopano core, right?

    This forum uses markdown for formatting. in the full editor there are also shortcuts for it.

    @shruuf said in Cannot forward email with fetchmail to Kopano for one user:

    Authentication by plugin failed

    the plugin reference is due to the different user backends being implemented as plugins. this simply means that the user could not be authenticated.



  • Thank you.
