Recently I'm learning Sendmail in CentOS,But I have got some prombles when I am following the tutorial on youtube.
I have followed the steps in the video, but when I try to test the Sendmail with the mail command,Sendmail Response that:
example.com: Name server timeout
user@example.com... Transient parse error -- message queued for future delivery
user@example.com... queued
It seems that sendmail must have an MX record to deliver mail to the local virtual domain, which is not mentioned in the video.
