We have a 10M line.

This is in Sympa's TODO.
Hopefully it will be implented soon.

The initial password is a MD5 hash of the user's email and the srver's
secret (cookie). Once the person has subscribed to a list or customized
his preferences. His/her password is stored in the database.

Sympa encrypts password in Cipher::Saber library is installed.
If you have been using Sympa without this library, you probably
have uncrypted password in your database. To encrypt them, run
the crypt_passwd.pl.

Sympa can manage both types of passwords (crypted or not) in the
same db.
