Previously + we assumed that tags in the header were well-formed, and parsed the + element content after inspecting only the first char of the tag. + Assumptions at that stage could crash the receive process on malformed + input. + +JH/05 Bug 2215: Fix crash associated with dnsdb lookup done from DKIM ACL. + While running the DKIM ACL we operate on the Permanent memory pool so that + variables created with "set" persist to the DATA ACL. Also (at any time) + DNS lookups that fail create cache records using the Permanent pool. But + expansions release any allocations made on the current pool - so a dnsdb + lookup expansion done in the DKIM ACL releases the memory used for the + DNS negative-cache, and bad things result. Solution is to switch to the + Main pool for expansions. + While we're in that code, add checks on the DNS cache during store_reset, + active in the testsuite. + Problem spotted, and debugging aided, by Wolfgang Breyha. + +JH/06 Fix issue with continued-connections when the DNS shifts unreliably. + When none of the hosts presented to a transport match an already-open + connection, close it and proceed with the list. Previously we would + queue the message.
