Yes, my main reason for going with Sympa, back in the day, was that it 
used a database, while Mailman did not - making it far more cumbersome 
when a single subscriber belonged to multiple lists.

For Mailman 3, the documentation says:

"Mailman uses the SQLAlchemy ORM to provide persistence of data in a 
relational database. By default, Mailman uses Python’s built-in SQLite3 
database, however, SQLAlchemy is compatible with PostgreSQL and MySQL, 
among possibly others."

Currently, Mailman is known to work with either the default SQLite3 
database, or PostgreSQL. (Volunteers to port it to other databases are 
welcome!)."
