Well, I found a similar problem on Unix.com forums, where someone was also receiving the dead.letter issue. Have you configured sendmail? If not, in the configuration file /etc/sendmail.cf, the line with DS must be modified and you must specified your mail server. You can add this server in the file /etc/host.

After the modification of your sendmail configuration, you restart the service :

refresh -s sendmail

or

stopsrc -s sendmail

startsrc -s sendmail -a "-bd"

HTH,

Also try sending mail from the command line with logging on (ie: mail -vvv -s Test root < /dev/null ) –  Demosthenex Feb 29 '12 at 16:48
