- "postmulti -p command" did not skip disabled instances.
- In the multi_instance_wrapper parameter, the expansion of
$command_directory and $daemon_directory was broken.
- The address_verify_poll_count parameter value was not made
stress-dependent by default. This defeated the purpose of making other
settings stress-dependent by default with Postfix 2.6.
- Milter applications would hang up after receiving an unexpected
SMFIC_HEADER (mail header) command. This problem happened with Milters
that (legitimately) do not send replies for SMFIC_RCPT (recipient
address) or SMFIC_DATA (start of message) commands.
- Core dump while an printing error message for a malformed %<letter>
sequence in LDAP, MySQL or PostgreSQL lookup table configuration.
- Mail with zero recipients was forever stuck in the queue. This happened
when "postsuper -r" was run after all the recipients of a message were
delivered (or bounced), but before the message was deleted from the queue.
- With hostnames such as 1-2-3-4, the valid_hostname() fuction did not
recognize the '-' as a non-numeric character, causing a legitimate name
to be rejected as "invalid".
- The VRFY command did not accept a mailbox address inside <>.
through all LWPs and duplicate locking overhead.
- Move sched_pstats() from soft-interrupt context to process 0 main loop.
Avoids blocking effect on real-time threads. Mostly fixes PR/38792.
Note: it might be worth to move the loop above PRI_PGDAEMON. Also,
sched_pstats() might be cleaned-up slightly.
seen in the wild. So, before accepting arbitrary strings from there,
validate at least slightly and ignore if the entries are not properly
0 terminated or contain controll characters.
