I am a newbie with linux and I am trying to configure sendmail on a CentOS box.
My sendmail in configured on a internal Lan ip machine where as the DNS server is on another machine. when i am trying to send email from the machine the log file show the error as 5.0.0 dsn:unavailable service but i can send emails to gmail using the same sendmail.
I am very much in need to solve this :(
Thanks in advance
