Hi, > /etc/postfix/main.cf > mailbox_size_limit = 0 > message_size_limits = 700M I am not sure if this is the problem, but I would like to suggest you to see if Postfix accepts this syntax. Here, my limit is written in bytes, like documentation. Just for curiosity, that "s" in "limits" is a typo? From postifx documentation ( site www.postfix.org ) message_size_limit (default: 10240000) The maximal size in bytes of a message, including envelope information. Thank you.
