📬 Emails
YunoHost integra un ecosistema completo de servidor mail, permitiéndote de alojar tu propia mensajería electrónica, y pues de tener tus propias direcciones email en algo@tu.dominio.tld.
The mail stack includes an SMTP server (Postfix), an IMAP server (Dovecot), antispam (Rspamd) and DKIM configuration.
Asegurarse de que la configuración esté correcta
Los emails son un ecosistema complicado y una multitud de detalles puedes impedir que funcionen correctamente.
Para validar que tu configuración es correcta :
- if you are self-hosting at home and not using a VPN, ensure your ISP doesn't block port 25 ;
- route ports according to this documentation ;
- carefully configure mail DNS records according to this documentation ;
- test your configuration using the diagnostic features ( Webadmin → Diagnosis → Email ). You can also use mail-tester.com; a score of at least 8~9/10 is a reasonable goal (be careful: only 3 tests per domain per day are allowed)
Clientes de mensajería
To interact with the email server (read and send emails), you can either install a webmail client such as Roundcube or Rainloop on your server or configure a desktop/mobile client as described in this page.
Los clientes Desktop o móvil tienen la ventaja de copiar tu emails en el equipo, así permitiendo la consulta desconectada de tus mensajes, y cierta protección frente a la posibilidad de un servidor averiado.
Configuration de los aliases de mensajeras y de las redirecciones automáticas
Mail aliases and forwards can be configured for each user. For instance, the first user created on the server automatically has an alias root@the.domain.tld configured—meaning that an email sent to this address will end up in the inbox of the first user. Automatic forwards may be configured, for instance if a user doesn't want to configure an additional email account and just wants to receive emails from the server on, say, his/her Gmail address (a copy of each email will be kept on the YunoHost server).
Another feature which few people know about is the use of suffixes beginning with "+". For example, emails sent to johndoe+booking@the.domain.tld will automatically land in the booking directory (lowercase) of John Doe's mailbox or in John Doe's inbox if the booking directory doesn't exist. It is a practical technique, for example, to provide an email address to a website, then easily sort (via automatic filters) the mail coming from this website.
Groups also can use alias features; by default, the group admins has aliases such as root@<domain.tld> and webmaster@<domain.tld>. More info on the groups and permissions page.
¿ Qué ocurre si mi servidor se pone indisponible ?
Si tu servidor se pone indisponible, los correos electrónicos mandados a tu servir se quedarán en una fila de espera por el lado del expedidor durante aproximadamente 5 días. El proveedor de hosting del expedidor intentará mandarte regularmente el correo, hasta que lo tire si no lo puede enviar.
