Not necessarily.

We store the forward/alias destination info in the same user DB,
where it may remain in-place indefinitely, as we also store a
boolean flag to indicate if it is active/inactive. Same with
'vacation' messages, account active/inactive, etc.

Our test to find the destination checks for flags, pulls the
appropriate destination fields from the DB.

SQL in our case.

cdb may need more separate (or more complex than average) cdb
files, but should still be faster, simpler, more robust than
running an RDBMS you may not otherwise need (we do anyway...).
