If Postfix announces a size limit of X, many SMTP clients won't
attempt to send larger messages, and Postfix won't accept a larger
message (and thus Postfix will not generate a bounce email message).
If you must configure Postfix to accept messages larger than X,
(and then return it to the sender) then you would have to use a
content filter to return the message with custom text. Postfix
does not have different templates for different error types; it
only distinguishes between delayed mail and other errors. Generally
one message can have more than one recipient and each of them may
have different errors, so error-dependent templates don't scale well.
If the files are large, then I would suggest sending the users a
temporary password for a website upload link. This gives the user
immediate feedback.
