This is not built into Postfix. It can be done only with plugins. * policy: You could use a Postix policy plugin that replies with REDIRECT when the message "size" attribute exceeds some limit. The target of REDIRECT would be an account with a different virtual mailbox. However, REDIRECT overrides ALL recipients, not just one, so it is no good when a message has multiple recipients. http://www.postfix.org/SMTPD_POLICY_README.html http://www.postfix.org/access.5.html * external content filter: best is a pass-through proxy that does not maintain its own queue. http://www.postfix.org/FILTER_README.html * milter: The Postfix Milter plug-in currently does not support the "replace recipient" action.
