Hi, I have a problem with my sendmail setup. Receiving mail is no problem, its just when I try an send something that I run into trouble. After running fetchmail, if I give the command mailq -v it shows me a list of the mails I just try to send with the following message: (Deferred: Name server: smtpserver.get2net.dk: host name lookup failure) mtpserver.get2net.dk being my isp's server. As far as I can see, my dns is setup properly, nslookup will find the smtpserver and give me the ip numbers. Can anyone help? Thanks Paul. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HEAD> <META content="text/html; charset=iso-8859-1" http-equiv=Content-Type> <META content="MSHTML 5.00.2314.1000" name=GENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=#ffffff> <DIV><FONT face=Arial size=2>Hi,</FONT></DIV> <DIV><FONT face=Arial size=2>I have a problem with my sendmail setup.
