This notification is triggered when the F5 Application Security Module (ASM) blocks an SMTP request because it violates security policies marked as blocking on the active WAF policy.

Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' F5-BIGIP-COMMON-MIB::bigipAsmSmtpRequestBlocked snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.3375.2.4.0.85
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
