It does not get sent.  It does not leave anything in any log that I can find.  It does not even seem to time out.  I think I waited at least five minutes while it tried to send a message to a virtual user @localhost.

I ran it without making any changes.  This is the output.

systemuser at openindiana:~/Downloads/Sendmail# sendmail -d60.5 -d27.2 -bv hacwebstore
map_lookup(dequote, systemuser, %0=systemuser) => NOT FOUND (0)
map_lookup(dequote, hacwebstore, %0=hacwebstore) => NOT FOUND (0)
alias(hacwebstore)
aliaswait: sleeping for 2 seconds (loopcount = 1)
aliaswait: sleeping for 4 seconds (loopcount = 2)
aliaswait: sleeping for 8 seconds (loopcount = 3)
aliaswait: sleeping for 16 seconds (loopcount = 4)
aliaswait: sleeping for 32 seconds (loopcount = 5)
aliaswait: sleeping for 60 seconds (loopcount = 6)

Then I made these changes to the sendmail.cf file, and restarted sendmail.

This was the output with the modified sendmail.cf:

map_lookup(dequote, systemuser, %0=systemuser) => NOT FOUND (0)
