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.
