%description
    Postfix is a new-generation Mail Transfer Agent (MTA) able to fully
    replace the Sendmail MTA. It is fully standards compliant and
    supports SMTP, ESMTP, LMTP over IPv4/IPv6 with optional TLS/SASL.

    Local specifics in this OpenPKG version:
    o Postfix delivers locally via Procmail
    o Postfix logs directly to the filesystem via OSSP fsl
    o Berkeley-DB dictionary support
    o PCRE matching support
    o Optional STARTTLS encryption support   (see package options)
    o Optional SASL2 authentication support  (see package options)
    o Optional SQLite dictionary support     (see package options)
    o Optional MySQL dictionary support      (see package options)
    o Optional PostgreSQL dictionary support (see package options)
    o Optional OpenLDAP dictionary support   (see package options)
    o Optional WHOSON dictionary support     (see package options)
