Caught by Jeremy; was wrong in (my) original commit, the dual-TLS work
had just renamed the variables and theoretically made it more visible.
I still missed it.
The server_sni context initialisation was setting the OCSP status
callback context parameter back on the original server_ctx instead of
the new server_sni context.
I guess OCSP and SNI aren't being used together in Exim much yet.

This was noticable when re-building as a non-privileged user
after installing as root; lookups/Makefile had been rebuilt
by root and when it was rebuilt again by the unprivileged user
`mv` demanded confirmation before overwriting the file.

Most of these are due to the changes in the logging of
ultimate timeout checks.
Test 0548 is more meaningfully affected. The test originally
failed to spot that the recipient-specific deferrals pushed
past the ultimate retry timeout.

Only do the ultimate address timeout check if there is an address
retry record and there is not a domain retry record; this implies
that previous attempts to handle the address had the retry_use_local_parts
option turned on. We use this as an approximation for the destination
being like a local delivery, as in LMTP.

Test 0254 submits a message to Exim with the header
Resent-From: f
When I ran the test suite under the user fanf2, Exim expanded
the header to contain my full name, whereas it should have added
a Resent-Sender: header. It erroneously treats any prefix of the
username as equal to the username.
This change corrects that bug.

When a queue runner is handling a message, Exim first routes the
recipient addresses, during which it prunes them based on the retry
hints database. After that it attempts to deliver the message to
any remaining recipients. It then updates the hints database using
the retry rules.
So if a recipient address works intermittently, it can get repeatedly
deferred at routing time. The retry hints record remains fresh so the
address never reaches the final cutoff time.
This is a fairly common occurrence when a user is bumping up against
their storage quota. Exim had some logic in its local delivery code
to deal with this. However it did not apply to per-recipient defers
in remote deliveries, e.g. over LMTP to a separate IMAP message store.
This commit adds a proper retry rule check during routing so that
the final cutoff time is checked against the message's age. I also
took the opportunity to unify three very similar blocks of code.
I suspect this new check makes the old local delivery cutoff check
redundant, but I have not verified this so I left the code in place.

Write a temp file with macro definitions from the makefile, and include it
from the doc sources. Pass the version to make from the perl script.
It is still needed to manually update the previous-version number and
changebar indicators (.new/.wen) manually.

Mostly just compiler-quietening rather than intelligent error-handling.
This deals with complaints of "attribute warn_unused_result" during an rpm
build for SL6 (probably for Fedora also).

If the dovecot protocol response doesn't include the MECH message for
the SMTP AUTH protocol the client has requested, that's not a protocol
failure, don't log it as such. Instead, explicitly log that it didn't
advertise the mechanism we're looking for. This lets administrators fix
either their Exim or their Dovecot configurations.
Also: make the Dovecot handling more resistant to bad data from the auth
server; handle too many fields with debug-log message to explain what's
going on, permit lines of 8192 length per spec and detect if the line is
too long, so that we can fail auth instead of becoming unsynchronised.
Stop using the CUID from the server as the AUTH id counter. They're
different, by my reading of the spec.
TESTED: works against Dovecot 2.1.10.
Thanks to Brady Catherman for reporting the problem with diagnosis.

Set the POSIX -e option on the #! line invoking /bin/sh.
If any of the sub-commands fail, the Configure as a whole should fail.

Broken in 4.80 release, commit 08488c86.
We need to leave $auth1 available after the authenticator returns, so
that server_set_id can be evaluated by the caller. We need to do this
whether we succeed or fail, because server_set_id only makes it into
$authenticated_id if we return OK, but is logged regardless.
Updated test config to set server_set_id; updated logs.

New log_selector, smtp_mailauth, to enable.

Rather than pass "where" around all the string-expansion calls I've
used a global; and unpleasant mismatch with the existing "where"
tracking done for nested ACL calls.

Avoiding confusion of 4.80.1 vs 4.81, we went with skipping to 4.82 instead.

CVE-2012-5671
malloc/heap overflow, with a 60kB window of overwrite.
Requires DNS under control of person sending email, leaves plenty of
evidence, but is very likely exploitable on OSes that have not been
well hardened.

Use a last octet which will highlight the hex nature in the example.
