Question : Sending email alerts

Hello,
    I have writen a script to check filesystem usage on the Solaris 2.6 system.

    This server resides in my Company's internal network. I am able to send email
     alerts to my work email address from this server(solaris 2.6) But i am not able to send email to
     my yahoo or hotmail account.

     If I run same script on another server (also in internal network but running solaris 9) I am able to send email to
     both my office email address and to my yahoo and hotmail accounts.

     Can someone please suggest something so that i am able to send email from Solaris2.6 server also.
     I am sure some settings are not correct to send outside of company. Please advise.

     Regards

OraCop

Answer : Sending email alerts

Please check for the "DS" entry in the /etc/mail/sendmail.cf file. If your Solaris server is not directly on the internet and/or does not have mailing capability it uses Relay host to send mails into the internet. The Relay host would have the capabilities
of sending e-mails into the internet.  Depending on the version of "sendmail" on your server, you may try to look for an entry like the one mentioned below,

# "Smart" relay host (may be null)
#DSmailhost.$m


Add an entry as follows to your /etc/mail/sendmail.cf,
DSyour-mail-host@your-company.com

Next, bounce your sendmail daemon.
To stop the sendmail daemon,
/etc/init.d/sendmail stop

To start the sendmail daemon,
/usr/lib/sendmail -bd -q15m

It would also be good to compare the sendmail.cf files on both your servers.
