SMTP credentials

Description

General

Documentation: https://tools.ietf.org/html/rfc5321
Summary: SMTP (Simple Mail Transfer Protocol) is a communication protocol for email transmission. This detector aims at catching SMTP credentials in the form of a host, a port, a username and a password, assigned to variables.
IPs allowlist: A range of allowlisted IP addresses can be specified on the server side.
Scopes: An SMTP server can enforce some restrictions on outbound traffic preventing some users to send emails.

Revoke the secret

Secret revocation consists in changing the user's email password.

Check for suspicious activity

Suspicious activity essentially consists of fraudulent email sent on behalf of a user and can thus manually be reported.
