• .dovecot.sieve.log file now includes year in the header.
• Change Sieve script result execution to delay definitive action execution to the end of a successful Sieve script execution session. This is part of an effort to solve problems with the Sieve duplicate test. As a side-effect, some rare temporary-error cases yield different results, in which partial failure is more likely.
