[Mailman-Users] domain "mail.mydomain.com" at email "myname at domain.com"

[Denny Zulfikar]

Dear all,

I am new user in this list. I have question that confusing me,

I setup mailman-2.1.11 by manual from source package.
My system is a mailserver using postfix virtual. hostname of the server is
"mail" with domain "domain.com".
My question are:
1. I had install the mail server successfully and also can send email to
other mail server such as yahoo and gmail.
In the recipient, email sent from my mail server identify as "from :
username at domain.com". but, why in mailman admin webinterface it listed as
username at mail.domain.com. ??
2. I cannot invite any person although in mailman admin web interface the
user already "successfully invited".

Are there something missing in my configuration.? please help.

BR,
Denny
