Rejection with status code 554 requires established TCP connection. Study mainlog to check whether connections are rejected. However, absense of numerous connections in ESTABLISHED state is a hint that rejection works. If you don't want TCP connections, use packet filtering on kernel level instead of Exim's configuration options. -- Eugene Berdnikov -- ## 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/
