Hello,
In my logs, I see that the host "starttls-virginia.proxy-research.com" regularly connect to my server and disconnect without doing anything. To not make it appear anymore in the logs, I tried to block it with this rule in smtpd.conf but it does not work : match \ from mail-from "proxy-research.com" \ for domain $DOMAIN \ reject Where $DOMAIN is "mydomain.tld". Where is my mistake ? Thanks for your help.
