[solved]The correct transfer of fetchmail to Postfix WITHOUT kopano-dagent
taumeister last edited by taumeister
I have a somewhat special construction.
Kopano server with Postfix [ with Ciphermail encryption ] with Fetchmail.
Kopano Server sends mails via Postfix to the outside. This works.
I can successfully sign, encrypt or send mails as encrypted PDF to the outside world. But Ciphermail should not be the focus here, that is anyway only a pimped postfix.
Fetchmail can also fetch my emails and if I enter as mta the Kopano-dagent in my fetchmailrc the mails will be delivered correctly to my Kopano users.
But I don’t want to give my mails directly to the dagent, because otherwise they won’t be decrypted correctly, that must be the Postfix ( Ciphermail ) again.
So I have to pick up my mails with Fetchmail and send Postfix to Kopano for delivery.
And that’s exactly my problem and I’ve tried so many things and so many snapshots in virtual machines that I’ve completely lost track of it.
I think one problem is that there are no local users with a mailbox, but only those that are stored in the mysql kopano database.
There are exactly two things here that I don’t know exactly ( probably much more, but two I’m aware of :=)
What is in my case the exact syntax for passing to the local postfix?
How is the postfix able to recognize if the mail should be sent to Kopano or if it should be sent to the remote mailbox?
So Postfix must be responsible for the internal as well as for the external mailboxes, which in my case are the same as well.
I don’t want to use a ’ Kopano-Fetchmail-Plugin’ solution and even with Ciphermail I can’t use the integrated Fetchmail solution because we don’t use the appliance.
Somebody must have had a similar problem, right?
Kopano sends via Postfix to external, fetchmail retrieves mails and delivers them to Postfix, it delivers again to Kopano.

I can provide you with more information.
Does anyone have an idea how I could proceed or check?
you always have to deliver your emails via the dagent. What you are looking for is delivering the mails from fetchmail to postfix and let postfix deliver to kopano.
This process is explained at https://documentation.kopano.io/kopanocore_administrator_manual/configure_kc_components.html#kc-postfix-integration
Thank you very much for your answer, but
damn…i was hoping i wouldn’t get that answer. i’ve worked my way through this configuration and just couldn’t get it done. One error results in the next error.
I will simply try it again.
Thanks first for your trouble
So I just rebuilt the part according to the instructions.
Now it’s like this:
I send a mail to firstname.lastname@example.org.
Fetchmail fetches the mailbox, sees there is an unread mail, apparently successfully forwards it to Postfix,
this one recognizes, aha,. for mydomain i am responsible, so i send this mail to the smarthost and not to my internal Kopano user.
It also seems logical to me how Postftix should know if the mail is responsible for the internal user name1@mydomain or for the external mailbox name1@mydomain.
Thank God, it seems to be read after the first run, otherwise I would have a loop here.
Do I have to tell postfix via fetchmail that this is only for internal distribution? That would seem logical to me…
You are missing the
is taumeister herebit in your fetchmail configuration
thanks for your help.
So, mails can now be sent via ciphermail ( postfix ) and fetchmail also passes correctly to Postfix.
So both directions work.
Thanks for this.
Of course, for each new solution at least one new or further problem is added :)
Now I get the mails from fetchmail to Postfix to Kopano, but apparently they are not decrypted by Postfix (Ciphermail).
So I can’t read mails that are signed and encrypted.
Public keys are of course available on both sides.
You don’t happen to know anything about Ciphermail and could help out?
No, I cannot help out with that. But make sure to post the answer here as well if someone else runs into this.
Felix, thanks for your help.
hmm how do i do this? …mark as solved

@taumeister I have asked the same question in the past. You need to edit your first posting
poohh how complicated a simple thing can be.
Why is there no ‘solved’ button?
