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 the any user the permission to do so (/var/spool/clientmqueue belongs to user and group smmsp). Later, another sendmail process, the sendmail localhost-only (FreeBSD default config) mail transfer agent (MTA) copies the messages from /var/spool/clientmqueue to /var/spool/mqueue and sends them to their destination. When files accumulate in /var/spool/clientmqueue, you probably don't run the sendmail localhost MTA, and thus the mails don't get send.
