problem with mail server / name server -- Linux

[jfall]

I have a mail server running.. i'm using sendmail... the incoming/outgoing mail servers are mail.domainname.com .. I am trying to send/receive mail with the pop account from a Windows XP computer which I have networked to my linux computer. I can receive mail fine, but when I try to send it says "Relaying denied, IP name lookup failed 192.168.10.1" .. so i'm guessing it is having trouble looking up my internal IP address of my windows computer.. anyone know what I can do to fix this?

Do you have an entry for the XP machine in /etc/hosts.conf?

That's about all I can say, knowing less than zero about sendmail...

By default sendmail won't relay mail from domains/hosts it can't resolve.

If you really want to use sendmail you should probably invest in the O'Reilly sendmail book and learn about all the config file directives.

I'm assuming that youre running the latest build of sendmail...its quite annoying when peeps ask for help but dont list the distro and version of the apps...we can't read your mind.

That said,
first thing that needs to be done is to rebuild the sendmail.cf file so that sendmail will listen on eth0 as well as localhost.

then, you will need to add your lan to the access.db file to allow relaying. If access.db is not used, then you'll have to set up hosts.deny and hosts.allow
