So what? This is about dbm vs. sqlite, not sqlite vs. other rdbms.
FWIW, there's a configurable lock timeout for sqlite (defaults to 5s),
which should be sufficient as long as you are not excessively
updating/inserting, which is unlikely in an MTA.

I'd even say, for most single host purposes sqlite could be faster than
conventional RDBMSs.
