"<" character, which should be a list-separator specification, we walked
off past the nul-terimation.
+JH/37 Bug 2341: Send "message delayed" warning MDNs (restricted to external
+ causes) even when the retry time is not yet met. Previously they were
+ not, meaning that when (say) an account was over-quota and temp-rejecting,
+ and multiple senders' messages were queued, only one sender would get
+ notified on each configured delay_warning cycle.

+JH/38 Bug 2351: Log failures to extract envelope addresses from message headers.
+
+JH/39 OpenSSL: clear the error stack after an SSL_accept(). With anon-auth
+ cipher-suites, an error can be left on the stack even for a succeeding
+ accept; this results in impossible error messages when a later operation
+ actually does fail.

+AM/01 Bug 2359: GnuTLS: repeat lowlevel read and write operations while they return error
+ codes indicating retry. Under TLS1.3 this becomes required.
