Linux Email Services - Sorting and Filtering Email with Sieve

The applications team at Eucalyptus and Lavender, Inc. has been getting a lot of emails with the subject “spam” in their applications user mailbox. You have been asked to create a filter so that any messages with “spam” in the subject are moved directly to the trash. To complete this lab: - Create a file in the `/home/cloud_user` directory named `.dovecot.sieve`. - Add a rule that will send any messages containing the word “spam” in the subject line to the trash. Good luck!
