Just enter the e-mail address and wait for the test results to appear.
There you will see the results of the different checks that are performed:
– Syntax check
If the format is incorrect it will be reported why. For example: unsupported characters, missing @-sign.
– DNS lookup
Any problems looking up the domain (the part after the @-sign) in DNS (Domain Name System) will be reported.
– SMTP verification
If possible an SMTP connection will be made to a mail server that is responsible for the e-mail, and any issues are reported.
Note that for some domains the SMTP servers don’t allow verification, so no information can be found. In this case the e-mail address may or may not exist.

EFF has released STARTTLS Everywhere: free tools to encrypt email between mail servers / Boing Boing

the Electronic Frontier Foundation — as part of its ongoing quest to encrypt the whole internet (see also: Certbot, Let’s Encrypt, HTTPS Everywhere, and related toold) — has just released STARTTLS Everywhere, an automated tool that generates the certificates, helps install and configure them, and double-checks the configuration to make sure everything is safe and secure.

Unless you run your own mail server, you can’t do anything with this: but you can (and should) send it along to whomever administers your email and get them to have a look. It’s totally free, and solves a real problem, widely observed in the wild, of mass email surveillance.

Mail server down

The squat!net email server is currently struggling. Emails might arrive very delayed or possibly not at all. Radar users may want to use radar-events [at] riseup [dot] net to stay in touch. The radar GPG key remains the same: ▻https://radar.squat.net/en/contact

JSON Mail Access Protocol Specification (JMAP)
▻http://jmap.io

JMAP is a new JSON-based API for synchronising a mail client with a mail server. It is intended as a replacement for IMAP. The specification is based on the API currently used by FastMail’s web app. It aims to be compatible with the IMAP data model, so that it can be easily implemented on a server that currently supports IMAP, but allows for reduced data usage and more efficient synchronisation, bundling of requests for latency mitigation and is generally much easier to work with than IMAP.

Introduction
►http://www.courier-mta.org/intro.html

The Courier mail server is a modular multiprotocol mail server that’s designed to strike a balance between reasonable performance, flexibility and features.
Features

Can be configured to function as an intermediate mail relay, or as a mail server that receives mail for multiple domains and makes it accessible to mail clients, or anything in between.
Web-based administration and configuration tool .
Local mailboxes can be accessed via POP3. The Courier mail server includes an integrated POP3 server.
Local mailboxes can be accessed via IMAP. The Courier mail server includes an integrated IMAP server.
A built-in IMAP/POP3 aggregator proxy. It is possible to distribute all mailboxes between multiple servers. A separate server (or a pool of servers) accepts connections from IMAP or POP3 clients, then connects to the right server based on the mailbox the connecting client is logging into.
Local mailboxes can be accessed via HTTP. The Courier mail server includes an integrated webmail server.
The webmail server includes a personal event calendar.
Uses an efficient maildir format as its native mail storage format. Some support is provided for legacy mbox mailboxes.

Plein d’aspects intéressants, dont une belle pérennité (►http://www.courier-mta.org/changelog.html), une config « web », un webmail, des paquets debian... Quelqu’un connait ?
