sourcetype notes
pps_mail_log This sourcetype will conflict with sendmail itself, so will require that the PPS send syslog on a dedicated port or be uniquely identifiable with a hostname glob or CIDR block if this sourcetype is desired for PPS.

Sourcetype and Index Configuration

Filter type

MSG Parse: This filter parses message content * NOTE: This filter will simply parse the syslog message itself, and will not perform the (required) re-assembly of related messages to create meaningful final output. This will require follow-on processing in Splunk.
