Did you mean DEFAULT_URL_HOST and DEFAULT_EMAIL_HOST?

Note that these should be defined as domain names, not IP addresses. IP
addresses may work in some contexts, but if you don't have a domain
name, you will have problems sending and receiving mail. Note these
are generic problems with mail, and not specific to Mailman.

In order to be able to send mail reliably, you need a non-generic
domain name with a fixed IP address and a rDNS pointing from that IP
to the domain name. Without these, you will find your mail blocked by
many services.

After defining DEFAULT_URL_HOST and DEFAULT_EMAIL_HOST in mm_cfg.py,
you need

VIRTUAL_HOSTS.clear()

to remove the Defaults.py values from the VIRTUAL_HOSTS dictionary, and

add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)

to add the new values.

Can you send mail from your laptop through the local Postfix? E.g.,
with Postfix's 'sendmail' command.

Can your laptop receive any mail at all, e.g. for a local user?
