Answer 1

This is your mail queue, most likely it's a program or programs sending mail(s) to users which your system doesn't know how to deliver.

you can check the output of mailq which may (or may not) show you what's in there, but this command depends entirely on how your system is configured.

As to what's generating them, it's most likely cron jobs.

Answer 2

If you don't care about loosing all your emails, only to stop sendmail:

service stop sendmail

/var/spool/clientmqueue is where emails are waiting for delivery. If there are problems with sendmail or it's configuration, this dir will be growing. Check your config files: /etc/mail/sendmail.cf and /etc/mail/submit.cf
