Their addresses are: smtp.acw-web.com. 3600 A 156.46.248.98 br01.acw-web.com. 3600 A 156.46.248.98 smtp.globaldialog.com. 43780 A 156.46.122.10 See that smtp and br01 have the same ip address? Now from your log your machine think that it is br01, so when it receives a mail message for the equinomical.com domain it looks in the dns and sees that there is a lower MX record (smtp.acw-web.com) for that domain, so it will try to send it there.... but it is the same machine so it will talk to itself... and sendmail don't like to talk to itself. :-) John -- John Hay -- John.Hay@mikom.csir.co.za
