I login as root I try send mail at shell # mail dowell@exper.dynserv.com Subject: test Test email at shell . cc: root@exper.dynserv.com I think the mail has been sent out. I setting dowell@exper.dynserv.com in Mozilla mail my Mozilla says there is no message on server :confused: :confused: after that I use Mozilla to send test mail, but Mozilla always ask me password, i'm sure I enter correct password¡£so I click cancel input password button.. I get one error message£º Sendmail of message failed The message could not be sent because connecting to SMTP server 192.168.1.5 failed.
