• Hi there

    We have been trying to setup Webapp and send mails. But we keep getting the following error
    "Unfortunately, kopano-spooler was unable to deliver your mail"

    Please help…

    Hi @ParsecSolutions,

    to be able to send mails you first need to configure a MTA (for example) Postfix, which takes the mails over from kopano-spooler.

    For users that are not too versed in Linux administration we recently launched Kopano One. It comes with a differing set of packages that have direct dependencies on packages that are otherwise only loosely coupled and therefore makes it easier to get started.

    After purchase of a matching subscription you’ll find install instructions at https://kb.kopano.io/display/WIKI/Kopano+One+on+Debian+10+-+quick+installation+instructions.

    PS: please include version information in future posts, as well as version of the OS.


  • HI @fbartels

    Currently we are using native setup for our in house development for study purposes.

    OS: Ubuntu 20.04
    WebApp: 3.5.14+dfsg1.orig-1
    Kopano Core:8.7.0

    Also MTA, we already have Postfix up and running.


  • Hi @fbartels

    Sending additional information if that helps. This is the error that we see when we try sending emails.

    Also, we are using LDAP authentication in this demo instance. As mentioned in my previous note, we are using Postfix which is up and running.

    The defualt Postfix setting was giving us an error. Hence we tried kopano-dagent. As this was also not working, we ended up using kopano-spooler package.

    I cannot really recommend to use the Kopano packages that come with Ubuntu/Debian. They are quite old and are missing fixes that we have since then published for our software. At the very least I would recommend you to request a trial serial from https://kopano.com/downloads-demo/.

    None of these components is a substitute for the others. They are all required to be used at the same time. kopano-spooler to pick up mails from the users outbox and forward to the mta. the mta (postfix) to send and receive mails from the outside world as well as local delivery and kopano-dagent to receive mails from the mta to put them into the users mailbox.

    We are currently stuck with the following error.

    warning: ldap:/etc/postfix/ldap-aliases.cf lookup error for <email_address>

    We are running this instance on AWS.

    @Thomas-James there are default policies at work in AWS that block outgoing connections on port 25. Based on the “connection timeout” that is logged I would say this is the case here.

    I am not exactly sure which cases can lead to the above error. Have you adapted the search term to your ldap tree. Do you have ldap at all? Can the credentials that you are using for postfix bind to the tree and search it?
