I recently set up a mailing list with mailman. I have been unable to send email to the list using the email address assigned based upon the default settings. I continuously receive a failed delivery message. The address that it is attempting to send mail to (or that it instructs subscribers to send mail to) is as follows:
mylist_mydomain.com@server29.totalchoicehosting.com
I currently have three subscribers, two of which I added manually and one in which I subscribed through the subscribers' site.
Thanks in advance.
