on my system the dagent can’t deliver mails exceeding some kind of limit in size. In the logfile i can find errors like this:
Fri Dec 7 13:03:39 2018: [error ] [ 5264] Unable to deliver message to “username”: too big (80040305)
Fri Dec 7 13:03:39 2018: [error ] [ 5264] Unable to deliver all messages for server “file:///var/run/kopano/server.sock”
I’ve searched the documentation and man pages for a hint how to configure (and raise) the message size limit and found nothing - can anybody point me in the right direction please?
