This is wrong, because it relates to the incoming message (and + probably the interface on which it is arriving) and not to the outgoing + callout (which could be using a different interface). This has been + changed to use the value of the helo_data option from the smtp transport + instead - this is what is used when a message is actually being sent. If + there is no remote transport (possible with a router that sets up host + 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: + (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. + (b) There were several signed/unsigned issues. I just did the minimum + hacking in of casts. There is scope for a larger refactoring. + (c) The code used strcasecmp() which is not a standard C function. + Replaced with Exim's strcmpic() function. + (d) The code set only $1; it now sets $auth1 as well. + (e) A simple test gave the error "authentication client didn't specify + service in request". It would seem that Dovecot has changed its + interface.

Suppose the + address A is aliased to B and C, where B exists and C does not. Without + -v the output is "A verified" because verification stops after a + successful redirection if more than one address is generated. However, + with -v the child addresses are also verified. Exim was outputting "A + failed to verify" and then showing the successful verification for C, + with its parentage. It now outputs "B failed to verify", showing B's + parentage before showing the successful verification of C. + +PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to + look up a TXT record in a specific list after matching in a combined + list. + +PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and + RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when + they consult the DNS. I had assumed they would set it the way they + wanted; and indeed my experiments on Linux seem to show that in some + cases they do (I could influence IPv6 lookups but not IPv4 lookups). + To be on the safe side, however, I have now made the interface to + host_find_byname() similar to host_find_bydns(), with an argument + containing the DNS resolver options. The host_find_byname() function now + sets these options at its start, just as host_find_bydns() does. The smtp + transport options dns_qualify_single and dns_search_parents are passed to + host_find_byname() when gethostbyname=TRUE in this transport. Other uses + 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. Exim version 4.63
