Escape character is '^]'. 220 pve.xxxxx.ru ESMTP Postfix (Debian/GNU) GET / HTTP/1.0 221 2.7.0 Error: I can break rules, too. Goodbye. Connection closed by foreign host. Postfix does not violate SMTP protocol (with "421 4.7.0" response), and its authors definitely have sense of humor. :) -- 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/
