[*] bug resolved and functionality improved


Parallels Plesk Panel 9.5.4

  1. [-] Issue resolved: An IP address could not be added to the mail server white list if it was in DNS zone file.

  2. [-] Issue resolved for Postfix: Messages sent to several mailing lists with Postfix were actually delivered to only one mailing list.

  3. [-] Issue resolved for Postfix: mail server bounced mail messages sent to a domain with mail service turned off and mail to non-existent users bounce set up, instead of redirecting the mail to an external mail server defined with MX record in the DNS zone.

  4. [-] Issue resolved for Postfix: sqlite3 error appeared in log files upon an authentication with the CRAM-MD5 method, while the authentication was actually successful.

  5. [-] Issue resolved: The spam training process "spammng" occupied all memory on the Plesk server, and as a result the Spam Filter Training tab was shown incorrectly.

  6. [-] Issue resolved: Reduced upgrade time on servers with a lot of mailboxes.

  7. [-] Issue resolved for Qmail: If there were a redirect and a mail group configured on a mailname to point at the same e-mail address, upon the redirect removal, the address was removed from the mail group as well. For details, see http://kb.parallels.com/en/6072

  8. [-] Issue resolved for Postfix: Plesk changed the order of "smtpd_client_restrictions" rules that were added manually to the Postfix configuration file if black list was enabled via Plesk GUI. For additional details, see http://kb.parallels.com/en/9062.

  9. [-] Issue resolved for Postfix: Now Plesk strictly configures Postfix for using IPv4.

  10. [-] Issue resolved: SPF spam protection worked incorrectly: all messages were resolved only as "neutral" or "pass", and local rules were ignored — a default whitelist was always used.

  11. [-] Issue resolved for Qmail: Neither successful nor failed CRAM-MD5 authentications were added to mail server log files.

  12. [-] Issue resolved: A domain alias was still scanned for spam even though spam filtering was turned off for the mail account. For more details, see http://kb.parallels.com/en/9278.

  13. [-] Issue resolved for Qmail: Mail handlers were used for local deliveries, which could lead to failing a message delivery when it was sent to an alias on the same host.

  14. [-] Issue resolved: When greylisting was enabled, it rejected the mail messages that users authorized via SMTP tried to send to local and remote recipients.
