Hi everyone,

This is my CONTAINERFILE for Bind9:

 undefined

    
FROM debian

ENV LC_ALL C.UTF-8

# Update and upgrade system
RUN apt-get update -y && apt-get upgrade -y && apt-get dist-upgrade -y

# Install BIND 9 and sudo (for debugging if needed)
RUN apt-get install -y bind9 bind9-dnsutils bind9-libs bind9-utils sudo

# Configure permissions for BIND directories
RUN mkdir -p /var/cache/bind /var/lib/bind /var/log/bind
RUN chown -R bind:bind /var/cache/bind /var/lib/bind /var/log/bind
RUN chmod 664 /var/cache/bind /var/lib/bind /var/log/bind
RUN chmod -R 664 /var/cache/bind /var/lib/bind /var/log/bind

# Create and configure log files

I am trying to setup my own lemmy server. I used ansible.

I can access my server via my domain just fine. But emails are not working.

First i had my mail and mx records pointing to privateemail via namecheap.

Then i tried using cloudflare email routing and their mx records.

neither worked for me with error connecting.

I thought maybe using dovecot? But self hosting email is new to me

I was hoping to use namecheaps privateemail but wasn’t sure how to get it working.

The email account worked and can send / receive but Lemmy and postfix cannot communicate with it.

Now I have no Mx records as I’m not sure what I should be using I am sure I am missing something obvious but idk what

Any ideas ?
