Currently we are using a DNS service (GoDaddy), an email service (GoDaddy), and a hosting service (Squarespace). I want to start a mailman mailing list on this domain, but want to use yet another service to host it.
Currently traffic to the domain goes to squarespace. Email goes to Godaddy. I would like to setup a subdomain where both web traffic and email traffic go to the third (mailman) service. The subdomain would be something like: lists.domain.com.
I believe this is what I need to do:
Setup an "A" record
- Host: lists
- Points to: ip address of mailman server
- TTL: 1 hour
Setup a "MX" record
- Priority: 0
- Host: lists
- Points to: mailman server domain
- TTL: 1 hour
Can anyone please confirm whether this is correct or not? I really don't want to move forward with these changes before I can confirm that this won't disrupt the existing email@domain.com accounts as well as webtraffic to (www.)domain.com.

What you are proposing is correct, and should work without disrupting mailflow to your existing mail server.
I would suggest that you don't make your subdomain and the FQDN of your list server host the same - not because it won't work, but because it is confusing.
