* New upstream. - the *SQL clients did not uniformly choose the database host from the available pool - raise the "policy violation" flag when a client request exceeds a concurrency or rate limit. - don't do smtpd_end_of_data_restrictions after the transaction failed due to, e.g., a write error. - two messages could get the same message ID due to a race condition. This time window was increased when queue file creation was postponed from MAIL FROM until the first accepted RCPT TO. The window is closed again. - the queue manager did not write a per-recipient defer logfile record when the delivery agent crashed after the initial handshake with the queue manager, and before reporting the delivery status to the queue manager. - moved code around from one place to another to make REDIRECT, FILTER, HOLD and DISCARD access(5) table actions work in smtpd_end_of_data_restrictions. PREPEND will not be fixed; it must be specified before the message content is received. * Updated Italian translations. Closes: #336925 * Swedish translations. Closes: #339746 * Switch to libdb4.3.
