This is a comparison of mail servers: mail transfer agents, mail delivery agents, and other computer software that provide e-mail services. Unix-based mail servers are built using a number of components because a Unix-style environment is, by default, a toolbox operating system. A stock Unix-like server already has internal mail, more traditional ones also come with a full MTA already part of. Jan 15, 2020 Before moving to the Mac, I used quite a number of Windows and Linux email clients, including Netscape Mail (which later turned into Mozilla Thunderbird), Outlook, Evolution and Opera Mail. When Gmail was launched I immediately became a fan and appreciated the huge amount of space they gave me, as well as the smart features of their web app. Jan 17, 2019 1. This native Mac program, known as Apple Mail, Mail.app, or just Mail, is a no-nonsense email client that supports all your accounts in a smart and straightforward UI. Apple Mail is the best email client for users that want simple, old-fashioned email organization with solid filing and archiving functions and not too many extra.
- Apple says it is aware of an email encryption bug in macOS Catalina.
- It plans to fix the problem in a future update.
- The problem meant that in certain cases, emails were being stored locally as unencrypted files.
Apple has said it is aware of an email encryption bug in macOS Catalina, and that it plans to fix the problem in a future update.
As reported by The Verge, a vulnerability was discovered by Apple IT-specialist Bob Gendler in Apple's Mail application for macOS. Whilst exploring how macOS and Siri curates information to suggest to users, he discovered that Mail and other apps store information which Siri uses to tailor its suggestions. One file, snippets.db, was apparently storing unencrypted text of emails that should have been encrypted. Even after removing the private key so as to prevent him reading encrypted emails, he found that the text of the email could still be viewed in snippets.db. The problem reportedly affects Catalina, Mojave, High Sierra, and Sierra.
According to the report:
Apple tells The Verge it's aware of the issue and says it will address it in a future software update. The company also says that only portions of emails are stored. But the fact that Apple is still somehow leaving parts of encrypted emails out in the open when they're explicitly supposed to be encrypted, obviously isn't good.
The Verge also notes that the issue, whilst concerning, may have only affected a very small number of people.
You need to be using macOS, Apple Mail, be sending encrypted emails from Apple Mail, not be using FileVault to encrypt your entire system already, and know exactly where in Apple's system files to be looking for this information. If you were a hacker, you'd need access to those system files, too.
You can stop Siri collecting emails in snippets.db by going to System Preference > Siri > Siri Suggestions and Privacy > Mail. Simply unselect 'Learn From this App.' Gendler suggests that this will not remove any older emails that may have already been stored, those will need to be deleted manually. Turning on FileVault will also ensure everything on your Mac is encrypted.
As The Verge notes, this vulnerability won't affect many people but does call into question Apple Mail's encryption. Gendler also said:
'It brings up the question of what else is tracked and potentially improperly stored without you realizing it.'
There is no indication as to a timeline for Apple's fix, so if you're concerned about this bug just now, FileVault and Siri's Privacy settings are the way to go.
