No.  But a socketmap lookup passed through MIMEDefang down into the Perl code
is something like 10x to 1000x slower than a Berkeley DB lookup.

(Side note: I'd love to see Sendmail support Dan Bernstein's "CDB" databases;
our tests indicate they are much faster than Berkeley DB.  Maybe that's a
project for the future...)
