Email server ...behind a firewall.
Dns is obtained from another server.
I have confused myself so please be patient!!!
our domain is www.xxxx.net
sendmail is configured to "present system as xxx.net.
the hostname is mail.xxx.net
when users send mail from outlook express the mail reaches it's destination as someone@mail.xxx.net.
before we switched our isp the mail went out as ...someone@xxx.net
i want the mail to be someone@xxx.net.
What have i done wrong?? is the firewall configured wrong...sendmail???
www.dnsreport.com
testing with someone@xxx.net is good.
testing with someone@mail.xxx.net is a no go.
if i am correct ..when users send a email and it goes out with a reply to someone@mail.xxx.net we won't get our mail???
Thanks
Solved! Go to Solution.

Re: Sendmail domain
My sendmail.cf is xxx.net.
"Second, check your DNS (or any other way that you use to resolve name) and verify that you MUST resolve first the name xxx.net and after the name server.xxx.net. "
I believe you are correct!! I will check on Mon. with our provider....we are not hosting are own DNS.
Thanks again!! I can stop second guessing my self!

Re: Sendmail domain
But.
This is overridden by the DNS setting for the IP address on the public Internet.
But sendmail still says who the mail is from.
This can be set and fine tuned with sendmail macros.
Cwinvestmenttool.com
also see the masquerade as.
See the attached script which among other things builds the sendmail.cf file.
