2018-04-13DKIM downgrade example again; this time debuggedPhil Pennock
As well as previous commit's `len_3` -> `length_3`, we were missing braces around the expansion operator, resulting in trying to dereference an unknown variable `$length_3`, and we were missing the outer braces from the `or` expansion condition. We really need a better way to test ACL expansion without a full harness. :( This bug-fixed version is now running on my system.

2018-04-11Mention MTA-STS in DANE context; nit fixesPhil Pennock
Did an audit of text changed since commit 6aa6fc9c5 to look for issues which stood out, fixed those. Spelling mistakes, markup issues, minor grammatical infelicities. The public/private CA stuff in the DANE text might push people away from public CAs, but the existence of MTA-STS means that one of those is probably the best choice. Mention what exim.org does, to provide slightly firmer guidance without pressure. List the `dkim_hash` values, `sha512` appears to be new since that text was last touched.
2018-04-11Doc: website updates and so forthPhil Pennock
I've added <https://downloads.exim.org/> as a new vhost which doesn't reference FTP and loses the `/pub/exim` prefix. Fixed various other outdated claims and documented Jeremy's PGP key as the main key for releases, with mine (Phil's) and Heiko's as fallbacks. Mention the `.xz` files.

2018-04-08OpenSSL: Revert the disabling of the session-cache. Bug 2255Jeremy Harris
Session cacheing is never useful, as we use a new context for every TLS startup. However, removing the support triggers odd behaviour from Outlook Express (only when there is an IMAP server on the same machine as Exim): an initial connect from the OE client fails, the immediate retry works.

2018-03-31Docs: tidy the ChangeLog fileJeremy Harris
2018-03-28Implement dane_require_tls_ciphers (theoretically)Phil Pennock
It compiles with OpenSSL, on Darwin (if restore Darwin OS). It doesn't crash immediately, but more testing is needed from a place where port 25 is not just blocked.
2018-03-28Document new dane_require_tls_ciphersPhil Pennock
Haven't written the code yet, but writing the docs first helped me affirm that this makes sense and feels clean. Code in next commit.

2018-03-23Address jgh notes re OpenSSLPhil Pennock
* `/usr/local` is fair, on Linux, but I deliberately picked something specific to OpenSSL to make the context clear and limit bad interactions with other locally-installed software. * `RPATH` and `RUNPATH` are not the same and are deeply twisty in their interactions. <https://blog.qt.io/blog/2011/10/28/rpath-and-runpath/> is a decent summary.

2018-03-16openssl: use += for LDFLAGS, drop env PC docsPhil Pennock
Using `LDFLAGS=` instead of `LDFLAGS+=` will stomp over an earlier setting of LDFLAGS, and the DMARC support is now further up in `src/EDITME`, thus likely to get stomped upon. Rather than continue to document using `PKG_CONFIG_PATH` via env, the in-Local/Makefile support has been around for a little while now, so go ahead and make that the only way we suggest here. Add a mention of _why_ we use both `USE_OPENSSL_PC` and `LDFLAGS`.
