    A whole buncha' links with contradictory information on how to properly set up a mail server ;-)

    Disclaimer - My primary goal is to add proper Spamassassin (SA) filtering to an existing Postfix / Dovecot / roundcube installation, i.e.:

    • use SA as a milter (mail filter) to attribute a spam score to incoming mail
    • keep SA up-to-date
    • train SA with spam/ham from the users' virtual mailboxes
    • train SA according to user decisions (actual user or trained mail client with automatic/trained spam detection)

    Here we go!

    Discussion de fond sur l'auto-hébergement de code source via Git :

    • mise en place d'une interface d'administration web,
    • fonctionnalités couvertes : granularité des droits, CI, wiki,
    • simplicité d'utilisation,
    • réactivité,
    • interactivité avec la communauté / cadre d'utilisation.
