When I send mails in the mails header it says:

X-Authentication-Warning: machine_name: local_user set sender to email@domain.com using -f

Now, I have tried to put the local user's name and email (both) in the /etc/mail/trusted-users list. But it didn't help.

Then, I tried to put the local user's name and email in /etc/mail/sendmail.cf in the trusted-users part:

Temail
Tlocal_user

That didn't help as well.

Then I tried to put the local user's name and email in /usr/share/sendmail/cf/openbsd-proto.mc
and did:

m4 /usr/share/sendmail/cf/openbsd-proto.mc > /etc/mail/sendmail.cf

That didn't help either.

I'd be glad if anyone please let me know what else to do.

Noir.

how can i send mail without having a domain name?

what's the definition for spam mail?
can't i send mail by using @[xxx.xxx.xxx.xxx] and not be rejected by firewall?

not necessarily, according to RFC 822:

Quote:

Domain-literals which refer to domains within the ARPA Inter-
net specify 32-bit Internet addresses, in four 8-bit fields
noted in decimal, as described in Request for Comments #820,
"Assigned Numbers." For example:

[10.0.3.19]

Note: THE USE OF DOMAIN-LITERALS IS STRONGLY DISCOURAGED. It
is permitted only as a means of bypassing temporary
system limitations, such as name tables which are not
complete.

So with that in mind, alot of administrators just don't configure to allow literals.
