OPNSense Caddy

[nbrg_kr]

Good Morning,

I encountered a problem which i can´t solve.

We run an OPNSense Appliance with subscription.

Caddy is installed and behind runs a mailcow instance and a nextcloud instance.

Both a running fine with http/https and the mailcow eas functionality.

But E-Mail clients can´t connect to the mailserver using IMAP due ssl issues.

Is there a way to route the IMAP and TLS through caddy or do I have solve this with special rules ?

I am lost right now.

I hope someone can help me with this.

Thanks in advance.

Regards

Thomas

Imap ist nicht HTTP oder HTTPS.

Du kannst dem Mailcow Server auch ein gültiges Let's Encrypt geben mit dieser Option:
https://docs.opnsense.org/manual/how-tos/caddy.html#redirect-acme-http-01-challenge

Sobald das dem IMAP Dienst darauf zugewiesen ist, kannst du entweder eine Portweiterleitung in der Firewall machen, oder eine Layer4 Proxy Route:
