Hi everyone,
I’ve been using Mail-in-a-Box for years, and loving it! Huge thanks to @JoshData and the rest of the teamfor all their continued work! I especially love how easy it makes managing domains and their records.
I’m looking into setting up a couple mailing lists with Mailman. This would be on another server, using a subdomain. For purposes of stuff, let’s say the main domain is stuff.lol. The box is box.stuff.lol, and there would be a server running the Mailman suite at lists.stuff.lol.
Some googling suggested setting up Postfix on the Mailman server in a satellite configuration, though that’s all I’ve been able to find so far. Postfix configuration is a bit out of my depth. 
I’m wondering:
- Do I need a Postfix running on the Mailman server?
- If so, how should I configure it (aside from Mailman’s advice) since MiaB is managing the domain and it’s DKIM/SPF/… records?
Or, can I directly use the Postfix running on MiaB? I’m guessing not, since that would be messing with the configuration and would probably be overwritten by the next upgrade.
Thanks for all your help!
