What you need before you start

Every mail client asks for the same four things: a server address, a port, a security mode, and credentials. For Mila those credentials are always your full email address as the username (never just the part before the @) and the mailbox's own password -- the one set from the panel when the mailbox was created, or from a reset link. That password is separate from whatever your organization's owner uses to sign in to the Mila panel itself.

Incoming mail: IMAP or POP3

IMAP keeps your messages and folders on the server and syncs them across every device you check mail from -- read something on your phone and it shows as read on your laptop too. POP3 downloads mail to a single client and, by most clients' default settings, removes it from the server afterward. Unless you have a specific reason to want a single-device archive, use IMAP.

Protocol	Server	Port	Security
IMAP (recommended)	imap.mila.cx	993	SSL/TLS
POP3	pop.mila.cx	995	SSL/TLS

Outgoing mail: SMTP

Sending always goes through smtp.mila.cx, on one of two ports depending on what your client or network supports:

Port	Security	Notes
465	SSL/TLS (implicit)	Use this first -- most clients default here.
587	STARTTLS	Fall back to this if 465 is blocked, which some hotel, campus, and mobile-carrier networks do.

SMTP requires authentication with the same email address and password as incoming mail -- there's no separate "outgoing password."

ManageSieve (server-side filters) -- optional

Most people never need this directly: filters and rules created in the panel apply on their own. ManageSieve only matters if you're pointing a dedicated Sieve-script editor at your mailbox instead.

Server	Port	Security
imap.mila.cx	4190	STARTTLS

Auto-discovery

Some clients (Thunderbird is the best-known example) can look up connection settings for a domain automatically instead of asking you to type them in. If your client offers to auto-detect and lands on the same values as the table above, accept them -- they're equivalent to entering everything by hand. If auto-detection fails or guesses wrong, switch to manual setup and use this page as the reference. See DNS setup for mail for the records that make auto-discovery possible in the first place.

About webmail

Prefer a browser to a mail client? Every setting above still works exactly as described, but you don't have to configure anything to check mail from a browser instead -- see Using webmail for how to log in and what's available there.
