Would it be okay to add direction-specific versions of "max-message-size", e.g., "max-message-size-send” and "max-message-size-recv”?
Reason: My outbound email relay provider (amazonses) limits outbound message size to 10M. If I don’t set "max-message-size 10M” and accidentally send a larger message, then my SMTP-client thinks the message is “sent” even though the backend relay fails. Silent failures are unacceptable to me, so I set "max-message-size 10M”. But setting "max-message-size 10M” also limits inbound messages and I have a contacts that like to send large attachments from time to time. Fortunately they do receive a “server reject due to size” message, and so know to instead try again by sending a link to some file-service (e.g., dropbox), but apparently it’s enough of a hassle for them to complain about. Thank you for your consideration. Kent
