Quite. In fact, even DB3 is very much overkill for Exim. All Exim needs
is a simple indexed file access method. I was somewhat surprised to
discover, on encountering Unix systems other than Solaris (where I was
developing Exim), that such a thing wasn't entirely standard in Unix.
Indeed, some early packagings of Linux didn't contain any indexed access
method at all (to my great amazement).

Fortunately, that is nowadays generally true.

No, it can't. But it can use tdb, a "trivial database" which is very
simple (I understand).
Had I realized at the start that there was going to be this mess with a
zillion different DBM libraries, I might have done things differently.
