SOT: do not use -o flag above. It makes sendmail start "happily" even
when virtusertable is inaccessible.

Which of sendmail.cf based solutions below do you prefer?
a) "cleaner" but requiring small patch of *.m4 files used to generate
   sendmail.cf [ would require repeating patching after every sendmail upgrade ]
b) "messy" with many related entries in different maps but without patching

P.S.
Some question that may help to choose the best recipe:
1) How many virtual mailboxes do you support?
2) Do you keep dovecot's userdb in plain text file?
