Yes. That all should be correct.

Are you sending to the 'help' mailing list
(help at h1228898.stratoserver.net)?

What happens to the mail to the list. Is it returned as undeliverable?
If so, why?

Look in sendmail's maillog and see what sendmail did with the mail.

It means that sendmail is accepting mail via an SMTP connection FROM
Mailman and delivering it to the recepient addresses.

It does not say anything about whether or not sendmail knows how to
deliver mail TO Mailman or even if the mail gets to sendmail.

Note I just tried to connect to h1228898.stratoserver.net port 25 from
two different machines and was unable to connect. This means that at
least at this time sendmail is not listening for a port 25 connection
from the outside, and thus mail from the outside cannot be delivered
to this machine.
