We need to ingest sendmail process generated maillog into Elasticsearch cluster. I have created latest installations of filebeat/logstash/elasticsearch stack on my test environment. I did Google search and found this is close to what I need:
However, those are for postfix. Right now I'm using sendmail, and I'm not sure how to change above resources to fit into sendmail maillog data ingestion. I also have opendkim process writing into same maillog as sendmail writes to.
Thank you,
