Unable to resolve smtp protocol

My Suricata found a lot of records with event_type=flow for destination port 25, but zero for smtp.


Some things that would help us determine what might be happening:

  • Suricata version in use
  • Suricata configuration file (by default is named suricata.yaml)
  • A pcap that demonstrates the issue

These items will help us get started and by posting them here, others in the community can offer help
