Cleanup: include unread byte count in the SMTP server's "lost
connection after DATA (xx bytes)" logging. Files: smtpd/smtpd.c.
20080629
Bugfix (introduced Postfix 2.2): multiple inconsistencies
in SASL support after introduction of TLS. The Postfix
SMTP server 1) complained about plain-text SASL configuration
details when SASL was forbidden for plain-text sessions,
and 2) ignored the smtpd_tls_auth_only parameter setting
when built without TLS support. Files: smtpd/smtpd.c,
smtpd/smtpd_check.c, smtpd/smtpd_sasl_glue.[hc],
smtpd/smtpd_state.c.
Some clarification about recipient address versus domain,
and recipients per message versus session. File:
proto/postconf.proto.
The description of SASL authentication attributes was
garbled. File: pipe/pipe.c.

If you upgrade from Postfix 2.4 or earlier, read RELEASE_NOTES-2.5
before proceeding.
Incompatibility with snapshot 20080629
======================================
When TLS support is not compiled in, the Postfix SMTP server no
longer ignores the "smtpd_tls_auth_only = yes" parameter setting.
Earlier Postfix SMTP server versions would announce SASL support,
and would accept SASL login or sender information.
Major changes with snapshot 20080629
====================================
The Postfix SMTP server's SASL authentication was re-structured.
With "smtpd_tls_auth_only = yes", SASL support is now activated
only after a successful TLS handshake. Earlier Postfix SMTP server
versions could complain about unavailable SASL mechanisms during
the plaintext phase of the SMTP protocol.
