Ah, this makes so much more sense... thanks for including the tcpdump output. This is not a problem of your sendmail installation. It's a misconfigured name server at bellsouth-hosting.net returning ServFail instead of NoData or NxDomain. See the reply of Gregory Shapiro to a similar problem at the following thread (please copy the URL to a single line if a mailer happens to wrap it in more than one line): http://groups.google.com/groups?q=%2Bauthor:shapiro+%2BAAAA+%2Bsendmail&hl=en&lr=&ie=UTF-8&oe=ISO-8859-1&selm=fa.llm8ijv.608c06%40ifi.uio.no&rnum=4 - Giorgos
