EMX in mail apps

Every mail app works with EMX; most need nothing but the address.

The settings

Your account password never goes into a mail app. Under Settings, Mail apps in the web client you make an app password per device, shown once, revoked on its own. A password made for the phone can be revoked when the phone is lost without touching anything else.

Apple: one tap

On an iPhone, iPad or Mac, press Apple profile in the same settings. EMX makes an app password for the device and hands you a configuration profile with the account inside; installing it sets up Mail. The profile is not signed, so the device says so once. Removing the profile removes the account; revoking the app password does the same from our side.

Thunderbird, Outlook and the rest

Type your address. Thunderbird and the apps that share its format read autoconfig.<your domain>; Outlook reads autodiscover.<your domain>; both names are CNAMEs to us that the DNS assistant in the admin interface writes with the other records of the domain. The domain's DNS also carries SRV records for IMAP and submission (RFC 6186) for apps that look there.

What the app sees

The folders are the ones in the web client, with their roles announced (SPECIAL-USE), so an app files sent mail and drafts in the right place without being told. Flags are shared: a message read on the phone is read in the browser, and the other way round, within the second. Snoozed and Screener are folders like any other to an app.

The shared mailboxes you are a member of appear in the app beside your own, with the rights you have in them.

A sealed mailbox cannot be read by a mail app: its messages are ciphertext that only the person's own devices can open, in the web client. The app is told so at sign-in.

EMX has no calendar and no contacts, so there is nothing to set up for CalDAV or CardDAV, and no Exchange ActiveSync: Outlook and the phone's mail app connect over IMAP.

Limits

Uploads over IMAP (a mail app filing a sent message, an import) count against the mailbox's storage and the message size limit, 50 MB. Sending from an app goes through the same rules as the web client: sender rights, the daily and monthly limits, DKIM signing.
