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.

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.

NB: this means a bare "X-ACL-Warn:" header is harder to add.

State a more general policy of PGP signing, mention trust paths, cite
the main public keyserver pool, provide a link to a trustpath display
between Nigel's key and Phil's.
Provide Phil's current PGP keyid (noting will change in 2013).
Bounce via a redirector, on Phil's security site, because:
(1) xfpt barfs on &url(..) where the URL contains an ampersand
(2) No ampersands means less debugging across various platforms
(3) The redirector is https: with a public cert, where www.exim.org
does not have a cert (with that name, at this time).
All keys cited in 0xLong form (16 hex characters).
Nits:
(1) URL is given with https:// on one line, the rest on the next
(2) using alt text does not give the URL in the .txt format, despite
the docs, because we build .txt from w3m -dump, so the HTML form is
used.
(3) Ideally, we'll get around to having https://www.exim.org/ exist and
be usable for this redirect.
Side-effects:
(1) My name is in The Spec for the first time. :)
