Hello Masters,
I want monitor outbound email (smtp port) to know which machine is causing my IP blocked by spamhaus (although Spamdyke, SPF and DMARC have been enabled).
How do I get the SMTP log ?
I check /var/log/qmail, and also maillog.
I found nothing.
Do I need to an extra software to do this ?
Thank you for your help.
Best regards,
Putude
