configure webmail address on mail.mydomain.com

[guizmoau]

hi there,

I am trying to find a way to configure the address on roundcube webmail to be available as a subdomain like mail.mydomain.com in the case of a multiple domain configuration.

How can I do so ?

Since mailinabox will self-update and overwrite your configs, so this is not recommended. The generated/active nginx file is in /etc/nginx/conf.d/local.conf, which periodically gets generated by templates mailinabox/conf/ folder. Those templates are at risk of being overwritten by an update.

Your safest bet would be to:

• create a dummy@mail.mydomain.com user, (this adds the mail.mydomain.com domain)
• use the admin panel's 'Web' option to point mail.mydomain.com to /home/user-data/www/mail_redirect
• create a php script /home/user-data/www/mail_redirect/index.php with contents:

header("Location: https://primarydomain.com/mail");
die();

When someone visits mail.mydomain.com, they will be redirected to your primary domain webmail.
