Tightening Default AIX Sendmail – disciplinux – I started looking at the default AIX configuration of sendmail for the SMTP Open Relay issues. Previously I had sent a configuration change to allow only specific relay-domains. However, it appears that the default sendmail configuration sets "PROMISCUOUS_RELAY" which overrides the RELAY-DOMAINS directive.
This is really interesting. Business people many times are interested in getting mail log files analyzed. To analyse mail logs they need various field to appera in mail logs. e.g. "From", "To", "Subject" etc from the sent email. By default sendmail logs From and To fields but it does not log Subject field. In this article you will learn how to enable sendmail to log "Subject".
