After manuel migration no internal mails via postfix

I have in my testroom a installation for testing the migration from 7.2 to 8.x. The migration script not working, so i do the manuel way.

Now I will test the sending and much more. In my log i found the error

pipe_command: execvp /usr/bin/zarafa-dagent: No such file or directory

OK - I open the of postfix and want to change the line to:

zarafa unix - n n - 10 pipe
        flags=DRhu user=vmail argv=/usr/bin/kopano-dagent -R ${recipient}

but i see, that the kopano-dagent is not in the /usr/bin directory.

What can I do that I can send internal mails (1. step of my tests)?

OK - Now I found the /usr/sbin/kopano-dagent.

I disable the entry in and change in the mail_command to the new path of dagent-

But now i have much errors like deferred (unknown mail transport error)

Hi @mykey0815 ,

yes the path changed for the binary (but it did so in the later 7.2 releases as well). Generally speaking I would very much recommend to switch to lmtp delivery instead of delivery via pipe (config is explained in the manual).

As for your

you probably still have some zarafa_ something in your
