Previously the next char, after a pair + was collapsed, was taken verbatim (so ^^^foo became ^^foo; ^^^^foo became + ^^\x00foo). Fixed to get ^\x00foo and ^^foo respectively to match the + documentation. There is still no way to get a leading ^ immediately + after a NUL (ie. for the password of a PLAIN method authenticator. + +JH/39 Bug 2691: fix $local_part_data. When the matching list element + referred to a file, bad data was returned. This likely also affected + $domain_part_data. + +JH/41 Fix daemon SIGHUP on FreeBSD. Previously, a named socket for IPC was + left undeleted; the attempt to re-create it then failed - resulting in + the usual "SIGHUP tp have daemon reload configuration" to not work. + This affected any platform not supporting "abstract" Unix-domain + sockets (i.e. not Linux). + +JH/42 Bug 2692: Harden against a peer which reneges on a 452 "too many + recipients" response to RCPT in a later response, with a 250. The + previous coding assumed this would not happen, and under PIPELINING + would result in both lost and duplicate recipients for a message. + +JH/43 Bug 2694: Fix weighted distribution of work to multiple spamd servers. + Previously the weighting was incorrectly applied. Similar fix for socks + proxies. Found and fixed by Heiko Schlichting. + +JH/44 Bug 2701: Fix list-expansion of dns_ipv4_lookup. Previously, it did + not handle sub-lists included using the +namedlist syntax.
