mailx to send email 1

[wlf]

Hi, Is it possible to use mailx to send email from solaris stand alone box via a cable modem

connection? I configued sendmail. I can telnet localhost. When I try mailx and it failed.

Following is the output. Thanks.


# mailx -v xxx@yahoo.com
Subject: Email Test
EOT
# xxx@yahoo.com... Host unknown (Name server: mailhost.: host name looku
p failure)
/dead.letter... Saved message in /dead.letter

the problem is the DNS configuration of your solaris. what is the content of your "/etc/resolv.conf"? this files contains the DNS servers to find server names.

Cheers.

Looks it's working, but needs valid sender domain. My sunbox is just a stand alone box wich is not configured DNS. How to solve the problem. Thanks. -wolf

- setup DNS on this host (this is what I recommend) or
- configure sendmail using local files and not DNS (see sendmail.org or sunsolve.sun.com for a coockbooks)

Thanks for your reply. I setup configration files as following output, anything else need to do? Thanks again.

# cd /etc

this is ok. sendmail will use dns even if you do not set hosts resolution in nsswitch.conf only to files (and not files dns)

Does comcast even let you host a mail server (ie sendmail)?
