とりあえず、人柱

Changes from 4.0.6b4 to 4.0.6b5:
——————————-
1. Process user and spool config files as user, not as root (fix
security hole reported by Jens Steube)
2. Added “xtnd_xmit” as a boolean option to permit/deny XTND XMIT
and ‘x’ as a command-line option to disable it. You should
disable it unless you really need it, and even then it is better
to move to SMTP AUTH.
3. popauth now opens trace file as user, not root (fix security
hole reported by Jens Steube); also umask now set.
4. Fix race crash on FreeBSD (thanks to Martin Haller).

Changes from 4.0.6b3 to 4.0.6b4:
——————————-
1. Fix core dump on 64-bit Solaris 2.8 [thanks to Kenny Nguyen]
2. Log facility set on command line now applies to daemon as well.
[Thanks to Helge Oldach]
3. ‘-y’ to set log facility on command line now works again.
4. Allow ‘-V’ as synonym for ‘-v’ (to see version).

Changes from 4.0.6b2 to 4.0.6b3:
——————————-
1. X-UIDL header no longer written when Update_status_hdrs is false
[thanks to Helge Oldach]
2. Now calling SSL_shutdown() again if it fails the first time.
3. Now logging TLS errors when compiled with debugging and debug is
enabled (instead of either) [thanks to Maks N. Polunin].
4. Config file now always closed (not just on error).
5. Ensure pam_close_session() is called to destroy kerberos tickets.
Otherwise dead tickets accumulate in cache directory which runs
out of space quickly on busy server. Problem noted and fix
suggested by Rodney McDuff ITS UQ. (Directory permissions on
ticket cache dir need to be 1777).
6. Always log “Servicing request” (instead of just when debugging is
on). This allows start of pop sessions to be logged always which
is useful for diagnosis of problems.
7. Worked around problem on some systems causing SIGALRM to be masked,
leaving hung pop processes which should have timed out waiting
for a command from the client.
[ Thanks to David Shrimpton for changes 4-7 ]
8. Now defaulting to “EXPIRE NEVER” instead of “EXPIRE 0”
