just closing off an old thread, since i finally found my tuit.
my problem was that i wanted to run validity checks on outgoing
mail, the failure of which would prevent the mail from being sent.
the (eventually) obvious, and simple, approach is to create
a wrapper for send, and assign it to sendproc. the wrapper
does the validation checks, and only invokes send if they pass.
essentially:
...
if [ "$1" = -force ]
then
shift
send "$@"
else
final_checks "$@" && send "$@"
fi
exit
of course, final_checks needs to be able to pick the 'file'
argument out from any arguments that might be passed to send,
but if i'm passing any, i'll probably use the -force option as well.
