It most certainly does, that would be configurable, but you can confirm that by yourself: look at the full headers of the email you receive, you should see some headers saying something like: Received: from mx2.freebsd.org (mx2.freebsd.org [188.8.131.52]) by mail.cs.ait.ac.th (8.13.1/8.12.11) with ESMTP id l5CFXURR030909 for <[EMAIL PROTECTED]>; Tue, 12 Jun 2007 22:33:34 +0700 (ICT) Now consider the top most of the Received-by headers, this top most one has been generated by your qmail server. Does it have an IP address associated to the the name of the sending machine (mx2.freebsd.org [184.108.40.206])? If yes, it means qmail did some DNS resolving. bests, Olivier _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
