Mail, calendar & contacts settings

Most clients (Thunderbird, Outlook, Apple Mail, Android) configure themselves — just enter your full e-mail address and password. If you need to do it by hand:

Incoming (IMAP)mail.jfarjona.com, port 993, SSL/TLS
Outgoing (SMTP)mail.jfarjona.com, port 35, STARTTLS
Usernameyour full e-mail address
Calendar (CalDAV)https://cal.jfarjona.com/ (server: cal.jfarjona.com, SSL, username = e-mail address)
Contacts (CardDAV)https://cal.jfarjona.com/ (same as above)

iPhone / iPad / Mac

Install the profile apple.mobileconfig (Mail + Calendar + Contacts in one step; you will be asked for your address and password). It is signed and shows as Verified. Variants: /apple.mobileconfig?domain=yourdomain (signed with your domain's certificate), /apple.mobileconfig?email=you@yourdomain&prefill=1 (address pre-filled, but unsigned — shows "Not Verified").

Thunderbird

Add account → type your address and password → it finds the settings automatically.

Outlook

Add account → type your address → Autodiscover fills the settings (choose IMAP if asked).
