Hi Everyone,
i recently found Mailcow and want to switch from another Docker Mailserver. My System is running with Docker Compose and i use Traefik as my Reverse Proxy. With my old Mail Solution i used Traefik Labels to assign Ports for smtp etc. For Traefik i configured the necessary Entrypoints and my config file looks like this:
#Entry Points configuration
entryPoints:
web:
address: :80
http:
redirections:
entryPoint:
to: websecure
scheme: https
websecure:
address: :443
smtp:
address: :25
submission:
address: :587
imap:
address: :143
imaps:
address: :993
smtps:
address: :465
With my old Mailserver i had one Container that needed all these Ports. I used these labels to assign them:
#SMTP Relay
- "traefik.tcp.routers.moo_smtp_relay.rule=HostSNI()"
- "traefik.tcp.routers.moo_smtp_relay.entrypoints=smtp"
- "traefik.tcp.routers.moo_smtp_relay.service=moo_smtp_relay"
- "traefik.tcp.services.moo_smtp_relay.loadbalancer.server.port=25"
#SMTPS
- "traefik.tcp.routers.moo_smtp_ssl.rule=HostSNI()"
- "traefik.tcp.routers.moo_smtp_ssl.entrypoints=smtps"
- "traefik.tcp.routers.moo_smtp_ssl.tls.passthrough=true"
- "traefik.tcp.routers.moo_smtp_ssl.service=moo_smtp_ssl"
- "traefik.tcp.services.moo_smtp_ssl.loadbalancer.server.port=465"
#SUBMISSION
- "traefik.tcp.routers.moo_smtp.rule=HostSNI()"
- "traefik.tcp.routers.moo_smtp.entrypoints=submission"
- "traefik.tcp.routers.moo_smtp.service=moo_smtp"
- "traefik.tcp.services.moo_smtp.loadbalancer.server.port=587"
#IMAP
- "traefik.tcp.routers.moo_imap.rule=HostSNI()"
- "traefik.tcp.routers.moo_imap.entrypoints=imap"
- "traefik.tcp.routers.moo_imap.service=moo_imap"
- "traefik.tcp.services.moo_imap.loadbalancer.server.port=143"
#IMAPs
- "traefik.tcp.routers.moo_imap_ssl.rule=HostSNI(*)"
- "traefik.tcp.routers.moo_imap_ssl.entrypoints=imaps"
- "traefik.tcp.routers.moo_imap_ssl.tls.passthrough=true"
- "traefik.tcp.routers.moo_imap_ssl.service=moo_imap_ssl"
- "traefik.tcp.services.moo_imap_ssl.loadbalancer.server.port=993"
I would like to do the same with Mailcow. Right now i created an override.yml for mailcow to assign ports 80+443 to mailcow-nginx. This works fine but i am curious and want to see if that works too. What would be the best way to make use of these Traefik Labels with Mailcow?
Greetings Eike
