i'm a newbie here. I already setup 2 domain using ISPConfig, e.g. www.pristronic.com.my
. The first domain www.pristronic.com.my
doesn't have any problems and working. But the second domain have error when receiving email.
If I sending email from email@example.com
, it's fine. But when I want to reply or to send a new message from firstname.lastname@example.org
, it has a problem:
This is an automatically generated Delivery Status Notification
Delivery to the following recipient failed permanently:
Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 9): 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
But sending and receiving is working between www.pristronic.com.my
What is the solution for this? Thanks.
