+      The SQLite library handles multiple simultaneous accesses to the database

       Note that you must set LOOKUP_SQLITE=yes in Local/Makefile in order to

+PH/04 The IGNOREQUOTA extension to the LMTP protocol is now available in both

+      lmtp transport there is a new Boolean option called ignore_quota, and in
+      the smtp transport there is a new Boolean option called
+      lmtp_ignore_quota. If either of these options is set TRUE, the string
+      "IGNOREQUOTA" is added to RCPT commands when using the LMTP protocol,
+      provided that the server has advertised support for IGNOREQUOTA in its
+      response to the LHLO command.

+PH/05 Previously, if "verify = helo" was set in an ACL, the condition was true
+      only if the host matched helo_try_verify_hosts, which caused the

+      tested the remembered result. Now, if a previous verification attempt has
+      not happened, "verify = helo" does it there and then.
