squirrelmail and smtp authentication

[Pol Hallen <deben@fuckaround.org>]

Hi all :-)

for long years I using squirrelmail without authentication (smtp).

Now I'd like migrate to smtp with ssl authentication, I already 
configured postfix to do this, so...

Do I need enter manually each credetials for each user? Or can I solve 
with other way? (I don't use mysql) - smtp db is saslpasswd2

thanks for help
