Over 3 Million Mail Servers without Encryption exposed to Sniffing Attacks.
As scans from the IT-security threat monitoring platform Shadowserver show, 3.3 million hosts are running POP3/IMAP services without TLS encryption enabled and expose usernames & passwords in plain text when transmitted over the Internet.

The map shows IMAP and POP3 mail servers without TLS.
Over three million POP3 and IMAP mail servers without TLS encryption are currently exposed on the Internet and vulnerable to network sniffing attacks. Almost 900,000 are based in the U.S., another 560,000 and 380,000 in Germany and Poland, the organization found and adding: “We see around 3.3M such cases with POP3 & a similar amount with IMAP (most overlap). It's time to retire those!” You can check out vulnerability reports for both POP3 email servers and IMAP email hosts on the Shadowserver Foundation site.
IMAP and POP3 are two methods for accessing email on mail servers. IMAP is recommended for checking emails from multiple devices, such as phones and laptops because it keeps your messages on the server and synchronizes them between devices. POP3, on the other hand, downloads emails from the server, making them accessible only from the device where they were downloaded.
The TLS secure communication protocol helps secure users information while exchanging and accessing their emails over the Internet through client/server applications. However, when TLS encryption is not enabled, their messages contents and credentials are sent in clear text, exposing them to eavesdropping network sniffing attacks.
ShadowServer advised all email users to check with their email service provider to be sure that TLS is enabled and the latest version of the protocol is being used.](https://friendica-leipzig.de/photo/preview/600/416546 "[ImageSource: ShadowServer]

HIGH: Vulnerable POP3 Report | The Shadowserver Foundation
This report identifies hosts that have a POP3 service running on port 110/TCP or 995/TCP without TLS support. This means that passwords used for mail access may be intercepted by a network sniffer.www.shadowserver.org
