Hello,
can you differ the email which will be checked by the domain? If it is
so you can do it like us.
We give our mailserver two ip, one ip for domain which will be virus
check and one for no check.
And the you make in the data acl part this
deny message = This message contains a virus:
($malware_name) please scan your system.
demime = *
malware = *
condition = ${if !eq{$interface_address}{192.168.0.2}}
regards
kai
