can't send email

[Lazydog]

Here is something else to think about. Is your mail server setup in DNS? Does it have a MX record? Most mail server are checking DNS for this and if it's not there then they are not accepting mail.

I use root to login and mail root myself a email , and then use mail command to check it's sent or not , finally , system return message No mail for root . How can I check the email status is sent or not ?

I'm the beginner to using Linux , pls give me some advise , and thank you for your help !
