Hi, You seem to have a problem with the dns server you’re using… ☺ try a nslookup first to see what server you’re using. Also, with sendmail you can do a sendmail –bv sales@intervideoinc.com to see what’s happening Hope it helps, Duarte ________________________________________ From: otrs-bounces@otrs.org [mailto:otrs-bounces@otrs.org] On Behalf Of Florent PREVOST Sent: quarta-feira, 14 de Setembro de 2005 16:21 To: otrs@otrs.org Subject: [otrs] smtp error ________________________________________ Hi all, I'm using OTRS 1.3.2 with fetchmail and sendmail.
