dagent error message: Unable to deliver message to "username": too big (80040305)

Hi,

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?

kind regards,

Christoph

You do not provide many details to work with. I’d say look in logging of kopano-server for more details. MySQL max_allowed_packet?

Thank you for the feedback - the hint about MySQL max_allowed_packet already did the trick… i completly focused on Kopano settings and did not have in mind, to look into MySQL settings.

kind regards,

Christoph
