Dear Everyone
I am having problem with Sendmail.
I've just installed Redhat Linux 9 and I want to use this Linux as my personal mail server and web server.
I'm currently testing the sendmail installed with the Linux installation.
I'm planning to upgrade or re-install it with the latest sendmail.
Anyway, currently I can send a mail from my notebook using the sendmail on my linux server to anyone, but if I send a mail from the Linux terminal the mail gets lost and is not delivered to the target.
I used the following to test the sendmail on the terminal.
# /usr/sbin/sendmail -v
sangjin89@hotmail.com < 1.txt
...
>>>QUIT
221 2.0.0 infosec.kut.ac.kr closing connection
(No error, but mail lost)
However, if I send a mail to another local server(same domain) the mail is delivered without any problem.
# /usr/sbin/sendmail -v
sangjin@kut.ac.kr < 1.txt
...
>>>QUIT
221 2.0.0 infosec.kut.ac.kr closing connection
(No error, Mail is delivered Correctly)
How do I solve this problem?
