[An on-line version of this announcement will be available at
http://www.postfix.org/announcements/postfix-2.7.5.html]
Postfix legacy releases 2.7.5, 2.6.11 and 2.5.14 are available.
These contain fixes and workarounds that were already included
with Postfix stable release 2.8.4.
Fixed with Postfix version 2.7.5, 2.6.11 and 2.5.14:
* Performance: a high load of DSN success notification requests
could slow down the queue manager. Solution: make the trace
client asynchronous, just like the bounce and defer clients.
* The local(8) delivery agent ignored table lookup errors in
mailbox_command_maps, mailbox_transport_maps, fallback_transport_maps
and (while bouncing mail to alias) alias owner lookup.
* Workaround: dbl.spamhaus.org rejects lookups with "No IP
queries" even if the name has an alphanumerical prefix. We
play safe, and skip both RHSBL and RHSWL queries for names
ending in a numerical suffix.
* The Postfix Milter client reported a temporary error instead
of "file too large" in three cases.
* Linux kernel version 3 support. Linus Torvalds has reset the
counters for reasons not related to changes in code.
Fixed with Postfix 2.7.5:
* The "sendmail -t" command reported "protocol error" instead
of "file too large", "no space left on device" etc.
