Hi,
I use the FW restrictions, but I can not block the relevant clients
from foreign. Therefore, I need to block already authenticated clients,
based on written:
"Sometimes it happens that my legitimate user has an infected computer
and occurs leak credentials, for example to Asia and then the attacker
from Asia through my server sends e-mails, because he is successfully
authenticated."
I have to receive e-mails also from Asia...
Lubo M.

Hello,
What about using iptables or other firewall ruling to rule out
connections for SMTP from those CIDR ranges?
Atenciosamente,
