* fixes CVE-2020-12783 (bsc#1171490)
* Regard command-line recipients as tainted.
* Bug 2489: Fix crash in the "pam" expansion condition.
* Use tainted buffers for the transport smtp context.
* Bug 2493: Harden ARC verify against Outlook, which has been seen to mix
the ordering of its ARC headers. This caused a crash.
* Bug 2492: Use tainted memory for retry record when needed. Previously when
a new record was being constructed with information from the peer, a trap
was taken.
* Bug 2494: Unset the default for dmarc_tld_file.
* Fix an uninitialised flag in early-pipelining. Previously connections
could, depending on the platform, hang at the STARTTLS response.
* Bug 2498: Reset a counter used for ARC verify before handling another
message on a connection. Previously if one message had ARC headers and
the following one did not, a crash could result when adding an
Authentication-Results: header.
* Bug 2500: Rewind some of the common-coding in string handling between the
Exim main code and Exim-related utities.
* Fix the variables set by the gsasl authenticator.
* Bug 2507: Modules: on handling a dynamic-module (lookups) open failure,
only retrieve the errormessage once.
* Bug 2501: Fix init call in the heimdal authenticator. Previously it
adjusted the size of a major service buffer; this failed because the
buffer was in use at the time. Change to a compile-time increase in the
buffer size, when this authenticator is compiled into exim.
