SMTP-relay Smarthost features

Prevent spam
When using an SMTP relay, it helps you by detecting and blocking outgoing spam before it is forwarded to the recipient's mail server. This reduces the likelihood of your IP address being associated with spam, which can result in blacklisting.

Authentication
Many SMTP relay servers require users to authenticate before accessing the service. This means that only authorized users are able to send emails through the relay, reducing the risk of abuse and spam.

Monitoring
SMTP relay can also assist in monitoring and managing outgoing emails. This allows the sender to prevent the transmission of malicious or spam-like messages and enables prompt response to any reports of blacklisting.
