Hi Community,

ich habe mir neulich mailcow als Mailserver aufgesetzt. Ich habe es hinter dem reverse Proxy Traefik am laufen dafür habe ich die Anleitung hier verwendet: Traefik v2.

Ich bekomme aber trotzdem im mailcow logs unter ACME diese Meldungen.

Dort steht Use SKIP_LETS_ENCRYPT=y in mailcow.conf to skip it permanently., das sollte doch nicht der Fall sein oder? Denn das ganze soll ja mit einem Zertifikat laufen.

Meine Frage ist jetzt, was muss ich machen damit ich das zum laufen bekomme?

Weitere Infos:
Meine aktuelle compose-compose.yml: (Diese Poste ich mit denn dafür musste ich die Netzwerk IPs ändern, da es sich mit einem anderen überlappt hatte.)

# Do _not_ use IP:PORT in HTTP(S)_BIND or HTTP(S)_PORT
# IMPORTANT: Do not use port 8081, 9081, 9082 or 65510!
# Example: HTTP_BIND=1.2.3.4

# Additional SAN for the certificate

# You can use wildcard records to create specific names for every domain you add to mailcow.
# Example: Add domains "example.com" and "example.net" to mailcow, change ADDITIONAL_SAN to a value like:
#ADDITIONAL_SAN=imap.*,smtp.*
# This will expand the certificate to "imap.example.com", "smtp.example.com", "imap.example.net", "smtp.example.net"
# plus every domain you add in the future.
#
# You can also just add static names...
#ADDITIONAL_SAN=srv1.example.net
# ...or combine wildcard and static names:
#ADDITIONAL_SAN=imap.*,srv1.example.com
#

# Obtain certificates for autodiscover.* and autoconfig.* domains.
# This can be useful to switch off in case you are in a scenario where a reverse proxy already handles those.
