Second domain cannot receive incoming email

[ariefaisalz]

hi,

i'm a newbie here. I already setup 2 domain using ISPConfig, e.g. www.pristronic.com.my and www.e-markplus.com. 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 saya@e-markplus.com to user@gmail.com, it's fine. But when I want to reply or to send a new message from user@gmail.com to saya@e-markplus.com, it has a problem:

This is an automatically generated Delivery Status Notification

Delivery to the following recipient failed permanently:

saya@e-markplus.com

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 and www.e-markplus.com.

What is the solution for this? Thanks.
