Summary : Redirect all mail sent from box to a single address (sendmail)

All,

Thanks to those who responded.  Bertrand Hutin's suggestion of looking 
at the SEnvToSMTP Sendmail rule set lead me to do something I've been 
putting off for years, namely delve into the world of Sendmail rewrite 
rules.  After a bit of trial and error (sendmail -bt is your friend 
here) I found that the following hard wired rule added to the default 
Solaris sendmail.cf file seems to do the trick :

<snip>
############################################
###  Ruleset 3 -- Name Canonicalization  ###
############################################
Scanonify=3

# handle null input (translate to <@> special case)
R$@                     $@ <@>

# <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Redirect all mail
DRrecipient@yourdomain.com
R$+                     $: $R # Hard coded recipient, see R macro above
# >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

# strip group: syntax (not inside angle brackets!) and trailing semicolon
R$*                     $: $1 <@>                       mark addresses
R$* < $* > $* <@>       $: $1 < $2 > $3                 unmark <addr>
R@ $* <@>               $: @ $1                         unmark @host:...
</snip>

In this case recipient@yourodmain.com is the hard coded recipient.

The 'R' macro definition is shown here just above the actual rewrite 
rule to make it easier to understand what it going on, but moving it to 
the top of the file is probably neater and more maintainable.

The O'Reilly 'Bat' book "Sendmail" is a wise investment for anyone who 
is interested in this.
