HISTORY file
============
20070331
Bugfix (introduced Postfix 2.3): segfault with HOLD action
in access/header_checks/body_checks on 64-bit platforms.
File: cleanup/cleanup_api.c.
20070402
Portability (introduced 20070325): the fix for hardlinks
and symlinks in postfix-install forgot to work around shells
where "IFS=/ command" makes the IFS setting permanent. This
is allowed by some broken standard, and affects Solaris.
File: postfix-install.
Portability (introduced 20070212): the workaround for
non-existent library bugs with descriptors >= FD_SETSIZE
broke with "fcntl F_DUPFD: Invalid argument" on 64-bit
Solaris. Files: master/multi_server.c, *qmgr/qmgr_transport.c.
20070421
Cleanup: on (Linux) platforms that cripple signal handlers
with deadlock, "postfix stop" now forcefully stops all the
processes in the master's process group, not just the master
process alone. File: conf/postfix-script.
Is your recent LDAP transport_maps cache patch included in this release?
Thanks
