Subject: [CentOS] configuring sendmails domain 

I tried editing sendmail.cf and changing the Dj line to X.com 
so any email originating from my machine would be X.com not m.X.com 
where m is machine name. 

I typed make in the /etc/mail directory and did service sendmail restart. 

This did not work. email still shows as m.X.com 

What am I missing so as to NOT have the machine name in the email address. 
I just want the domain. 

Thanks, 

Jerry

Editing the .cf file is not the way to do this sort of thing. Ensure you have the sendmail-cf package installed and make your changes to the /etc/mail/sendmail.mc file and then type 'make' to build the new .cf. Then restart sendmail. 


Incidentally, the .mc file has the necessary parameters in it that you may be looking for; 


dnl MASQUERADE_AS(`mydomain.com')dnl 
dnl # 
dnl # masquerade not just the headers, but the envelope as well 
dnl # 
dnl FEATURE(masquerade_envelope)dnl 
dnl # 
dnl # masquerade not just @mydomainalias.com, but @*.mydomainalias.com as well 
dnl # 
dnl FEATURE(masquerade_entire_domain)dnl 
dnl # 
dnl MASQUERADE_DOMAIN(localhost)dnl 
dnl MASQUERADE_DOMAIN(localhost.localdomain)dnl 
dnl MASQUERADE_DOMAIN(mydomainalias.com)dnl 
dnl MASQUERADE_DOMAIN(mydomain.lan)dnl 


Cheers.
