Red Hat :: Sendmail 8.13 - Can't Send Mail To Own DomainJan 13, 2010
i have running sendmail 8.13 on my red hat enterprise linux 5.1, but i have a problem. I can send a mail from my line command terminal to hotmail, gmail, yahoo and any of these, but i can't send mail to my own domain ([URL]), when i wrote a mail i get a reply from MAILER-DAEMON@localhost.localdomain that says that the message had pemanent fatal errors and shows as user unknown the mail was suposed to recive the message.
For example, if i send one mail from firstname.lastname@example.org to email@example.com the user2 does not recive any mail, but that doens not happens if user1 sends a mail to any hotmail address or gmail or any other. Besides i also can't recive on my server any mail to firstname.lastname@example.org or email@example.com (for example), so please tell me what do i do to get the mail.
