Sendmail Denied Access


I am having trouble sending some emergency log reports over email on rhl 9. When I send the mail to my email address , the provider sends back a mail that reports localhost.localdomain is not valid and rejects my message. I do not have a FQDN on this server but I want to be able to send messages to my email address. I have tried actually changing my name to a fake FQDN in /etc/hosts and it works but I have many other problems then.

Is there a way to configure sendmail to change the from address to something like "mydomain.com" so I can send messages to my email and not get rejected?

you must first of all have a valid FQDN for setting up a sendmail server and make it work. otherwise sendmail wont work. the way sendmail works is as follows. first it searches if the message is destined for the same domain.if it is then it delivers it to the local mailbox. otherwise it does a dns lookup for the mailserver of the destined domain. here ur amilserver looks upto ur isp's dns server. but since you dont have a domain registered u wont be able to send the mail. if u r configuring it for the local network u can do with a fake address. otherwise it wont help............vimal..
