The mailing list for listmasters using Sympa

[VTR <address@concealed>]

Thank you for the response. But I’m confused...

Our current MX is:

Host Name Mail Host

example.org example-org.mail.protection.outlook.com

I can’t change this since it points to M365 for routing.

And what is sympa-host.example.com? The public IP address of my Sympa server?

We created a subdomain for our Sympa instance, and it gets its own MX record.

MX example.com mail.example.com

MX lists.example.com sympa-host.example.com

Then you need to configure sendmail to receive and send as domain name you chose for your Sympa host, i.e. "lists.example.com".

I confess, I am weak on Linux and mail routing and but have been tasked with setting up Sympa for my company.

We have an Office 365 tenant with MX pointing to it. Let’s call the domain example.org. All mail gets delivered to it.

My company wants to set up a Sympa server for mail list management.

I installed Sympa on a variation of RHEL, installed SQLite, installed Sendmail, and am stuck here.

What value do I use for domain, since the primary is pointing to O365?

Do I set up a subdomain, like mail.example.org, and, if so, what DNS records do I need?

Sorry for newbie questions!

Thanks!
