Guess what, this morning i'm able to receive mails from email@example.com
and also from firstname.lastname@example.org
when those emails are sent from my ISPConfig server. But if i go on yahoo website and send mails to email@example.com
i can receive but if i send to firstname.lastname@example.org
from yahoo website, i cannot receive still, i think there is a big progress though.
should i still keep myorigin = mydomain in /etc/postfix/main.cf ?
