Can MailCleaner be configured to detect internal mail spam before sending it? example say domain1.tld have a user on that domain and the userPC is infected sending out spam can it be blocked if the same message is sent multiple times?
if so then what steps should be taken?
1. SMTP : SMTP checks - Scan relayed (outgoing) messages for viruses
2. You can play with settings of "Resources control"
3. You can do not include MTA for this domain in the list: Anti-Spam : global settings - Trusted IPs/Networks. But this may become cause of another problems
Have a nice day
