Symptoms

Systems with Sendmail services disabled may still have custom scripts and/or cron jobs which call mailx(1), and this results in unsent mail filling up the /var/spool/clientmqueue directory.

For Example:

bash-3.2# svcs -a | grep sendmail
disabled       Jun_14   svc:/network/smtp:sendmail
disabled       Jun_14   svc:/network/sendmail-client:default
bash-3.2#

bash-3.2# mailx -v -s test <USER>@<DOMAIN_NAME>
.
EOT
bash-3.2# <USER>@<DOMAIN_NAME>... Connecting to [127.0.0.1] via relay...
<USER>@<DOMAIN_NAME>... Deferred: Connection refused by [127.0.0.1]

bash-3.2#

bash-3.2# cd /var/spool
bash-3.2# ls -l *queue*
clientmqueue:
total 4
-rw-rw----   1 smmsp    smmsp          1 Jun 20 15:54 <FILENAME1>
-rw-rw----   1 smmsp    smmsp        731 Jun 20 15:54 <FILENAME2>
