    Hi Team

    Is it possible to change the maximum size of email to send / receive for a single domain?

    I have one client who regularly gets very large emails, and the sender is not able / wiling to use wetransfer or similar.

    Can someone please advise how this can be achieved - if it needs to be a global setting then so be it, but info on how to make that change would be useful too :)

    Thanks in advance

    message_size_limit = 0
    inside /etc/postfix/main.cf is the global setting for this (in bytes).

    Hi Marius

    thanks for that - is there a way to do it for specific domain? or does it have to be global?

    You would have to implement a milter (something like a policy daemon), so it would be quite complicated to do this per domain.

    Marius, I already have message_size_limit = 0, but outlook is telling me that "The Total Attachment Size exceeds the limit" any further thoughts?
