#   ConfigServer Threat Database › SMTP › 1 Day
#   Simple Mail Transfer Protocol
#   
#   These blocklists are maintained directly by ConfigServer and are
#   compiled from connection attempts against our SMTP honeypots, as
#   well as unauthorized access attempts targeting mail services we
#   operate.
#   
#   The threat feeds capture malicious SMTP activity across exposed
#   internet-facing email infrastructure, including automated scanners,
#   spam bots, and brute force attempts against mail submission and
#   relay endpoints.
#   
#   IP addresses included in this dataset have been observed attempting
#   actions such as credential brute forcing, mail relay abuse, spam
#   delivery attempts, and automated probing of SMTP services.
#   
#   Blocklists prefixed with `_1d` represent activity observed within
#   the most recent 24-hour period and reflect confirmed SMTP connection
#   attempts during that window, treated as high-confidence indicators
#   of malicious behavior.
#   
#   Blocklists prefixed with `_365d` are cumulative datasets covering
#   a one-year period and may include a higher rate of false positives
#   due to IP reuse, NAT, and infrastructure changes across providers.
