addresses), $smtp_active_hostname is used.
PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
- tweaks were necessary in order to get it to work:
+ tweaks were necessary in order to get it to work (see also 21 below):
(a) The code assumed that strncpy() returns a negative number on buffer
overflow, which isn't the case. Replaced with Exim's string_format()
function.
of host_find_byname() use the default settings of RES_DEFNAMES
(qualify_single) but not RES_DNSRCH (search_parents).
+PH/17 Applied (a modified version of) Nico Erfurth's patch to make
+ spool_read_header() do less string testing, by means of a preliminary
+ switch on the second character of optional "-foo" lines. (This is
+ overdue, caused by the large number of possibilities that now exist.
+ Originally there were few.) While I was there, I also converted the
+ str(n)cmp tests so they don't re-test the leading "-" and the first
+ character, in the hope this might squeeze out yet more improvement.
+
+PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
+ flag allowing group syntax was set by the header_syntax check but not
+ turned off, possible causing trouble later; (2) The flag was not being
+ set at all for the header_verify test, causing "group"-style headers to
+ be rejected. I have now set it in this case, and also caused header_
+ verify to ignore an empty address taken from a group. While doing this, I
+ came across some other cases where the code for allowing group syntax
+ while scanning a header line wasn't quite right (mostly, not resetting
+ the flag correctly in the right place). These bugs could have caused
+ trouble for malformed header lines. I hope it is now all correct.
+
+PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
+ with the "reply" argument non-NULL. The code, however (which originally
+ came from elsewhere) had *some* tests for NULL when it wrote to *reply,
+ but it didn't always do it. This confused somebody who was copying the
+ code for some other use. I have removed all the tests.
+
+PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
+ feature that was used to support insecure browsers during the U.S. crypto
+ embargo. It requires special client support, and Exim is probably the
+ only MTA that supported it -- and would never use it because real RSA is
+ always available. This code has been removed, because it had the bad
+ effect of slowing Exim down by computing (never used) parameters for the
+ RSA_EXPORT functionality.
+
+PH/21 On the advice of Timo Sirainen, added a check to the dovecot
+ authenticator to fail if there's a tab character in the incoming data
+ (there should never be unless someone is messing about, as it's supposed
+ to be base64-encoded). Also added, on Timo's advice, the "secured" option
+ if the connection is using TLS or if the remote IP is the same as the
+ local IP, and the "valid-client-cert option" if a client certificate has
+ been verified.
+
+PH/22 As suggested by Dennis Davis, added a server_condition option to *all*
+ authenticators. This can be used for authorization after authentication
+ succeeds. (In the case of plaintext, it servers for both authentication
+ and authorization.)
+
+PH/23 Testing for tls_required and lost_connection in a retry rule didn't work
+ if any retry times were supplied.
+
+PH/24 Exim crashed if verify=helo was activated during an incoming -bs
+ connection, where there is no client IP address to check. In this
+ situation, the verify now always succeeds.
+
+PH/25 Applied John Jetmore's -Mset patch.
+
+PH/26 Added -bem to be like -Mset, but loading a message from a file.
