Apple begins encrypting iCloud email sent between providers

Last month Apple confirmed that it would soon beef up encryption for iCloud email following a report detailing security flaws in major email services. While Apple previously encrypted emails sent between its own iCloud customers, now the company has enabled encryption for emails in transit between iCloud and third-party services for me.com and mac.com email addresses.

The change is documented on Google’s transparency website that shows the percentage of emails encrypted in transit for both inbound and outbound email exchanges (pictured below):

Growing number of iCloud users experiencing Mail delivery errors

Apple appears to be experiencing issues with its iCloud Mail service today, as a growing number of users report receiving a delivery error message from postmaster@mac.com for every email received (as pictured above). Most users report still being able to receive emails but also receiving the above error report for each email, while others claim the problem is only happening on specific accounts. An Apple support thread has been started with an increasing number of posters experiencing the same issue since this morning.

Reason: Error in sieve filter: Notify mailto: recipient is not a valid address Action: delivered Status: 2.0.0 (Error in sieve filter: Notify mailto: recipient is not a valid address).

There are also several users on Twitter complaining of the same error, but Apple ha yet to update its system status page to reflect the problems with Mail.

Anybody else using http://t.co/yMNQlQaozp email addresses getting mail delivery error messages after receiving actual emails? It’s annoying!
