postfix (2.4-20070123-1) experimental; urgency=low

  As of this version, Debian's postfix defaults to matching upstream
  behavior (introduced in postfix 2.0) in handling excessively long lines
  in a message:
    The Postfix SMTP client now breaks message header or body lines that
    are longer than $smtp_line_length_limit characters (default:  990).
    Earlier Postfix versions broke lines at $line_length_limit characters
    (default: 2048). Postfix versions before 20010611 did not break long
    lines at all.  Reportedly, some mail servers refuse to receive mail
    with lines that exceed the 1000 character limit that is specified by
    the SMTP standard.

  Those wishing the old behavior of never breaking lines should set
  smtp_line_length_limit=0 in /etc/postfix/main.cf, and be aware that they
  are not standard conformant.
