Hello,

thank you very much. Usually "Socket Error # 10061 Connection refused."-Errors are caused by blocking firewalls. Or wrong target settings (so the target, is actually not a SMTP-Server, or uses a different port). It could also be that the HELO is not accepted by the target SMTP-Server, or that the host of the PRTG Probe (running this SMTP-Sensor) is not allowed to connect to SMTP servers.

best regards.
