What’s new in 5.1.3:

  1. Delivery: Fixed a rare bug whereby the header of the mail will be incorrectly modified (an empty line is added) resulting in the mail becoming corrupted.
  2. Delivery: Fixed a bug would cause a mail to failed to be processed if the recipient has reached the mailbox warning threshold.
  3. Message tracking: Added logging if the message tracking specified is invalid.
  4. Message tracking: Fixed outgoing message tracking for a mail that’s received from an external sender but reforwarded out (by a forwarding rule). Previously such a mail will be tracked as an outgoing mail by the external sender. As a result you will see in the tracking account that the external sender has sent out an email! Now the mail will be recorded in the tracking mail as an outgoing mail by the forwarder.
  5. Webmail: Fixed the Javascript error that might appear when you sent an email as during the checking of missing attachments. The error would normally result in nothing happening when you try Send in the Compose page.
  6. Service: Fixed a bug whereby the parsing of a job file with message tracking job will cause an infinite loop. The main result of this is, if you stop the MailNow? service with such mail in the queue. And then when you try to start the queue again, the service will take a long time to start and will eventually fail to start. If you check the Service (under <MailNow?>/Logs/Combined/Service-YYYY-MM-DD.log) you will see that the last line would be “Trying to start QueueManager. Will take a long time if SMTPQueue is big” without it’s accompanying closing line that says “Successfully started QueueManager”
  7. Delivery: Implemented the “everyone” alias. Now you don’t need to manually maintain the “everyone” alias, it will have the same characteristic as in MailNow?! 4, i.e. when you send to this alias, all the users under that particular domain will receive the email.
  8. Delivery: Fixed a bug where an invalid display name for an email address in the mail header would throw an exception. This in turn will result in the email to be attempted to be delivered continuously by the Delivery module.
  9. Address book: Fixed a bug with regards to hiding/showing a user (or an alias) from the webmail and LDAP addresss book. Previously a user that’s considered not to be displayed (under the Permissions page in the WebAdmin) will not be hidden correctly.
  10. POP3: Added automatic protection against DOS attack. So if the same IP connects to the POP3 server many times in a short amount of space, the IP will be blacklisted temporarily.
