You could raise an RFE if you have a convincing case for it. FWIW, Postfix does drop connectiosn when the user-specified reject code is 421 or 521. Yes, server-initiated connection termination was not part of the original design of SMTP ~50 years back when the Internet was a kinder/gentler place. -- Viktor. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/

Shame although the 421 code sent the connection is not dropped which is a shame .. would have been a nice solution ..

The Exim SMTP server should ideally take note of that and also disconnect. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
