When submitting mail by using sendmail as a mail submission program,
sendmail copies all messages to “/var/spool/clientmqueue” first.
Sendmail is a setgid smmsp program and thus gives any user the
permission to do so (/var/spool/clientmqueue belongs to user and group
smmsp). Later, another sendmail process, the sendmail mail transfer
agent (MTA) copies the messages from /var/spool/clientmqueue to
/var/spool/mqueue and sends them to their destination.

6=110

/var/spool/clientmqueue is thus the holding area used by the MSP (Mail
Submission Protocol) sendmail instance before it injects the messages
into the main MTA (Mail Transport Agent) sendmail instance.

7=111

Sendmail will save the message in /var/spool/clientmqueue for safe
keeping before trying to connect to the MTA to get the message
delivered. Normally there would be a ‘queue runner’ MSP sendmail
instance which every half hour would retry sending any message that
couldn’t be sent immediately. Each message will generate a ‘df’ (message
routing info) and ‘qf’ (message headers and body) file. You can list out
all of the messages and their status by:
