Find files that have not been accessed for a while

Below one liner uses the find command to list files sorted by access time beyond the provided "number of days".

find </path/to/folder> -type f -atime +<number of days> -exec ls -ultr {} \;

This becomes handy if you want to do archive and cleanup of your web folders that have grown to a huge size.

sendmail access.db by example

The sendmail access database file can be created to accept or reject mail from selected domains.

Since "/etc/mail/access" is a database, after creating the text file, use makemap to create the database map.

# makemap hash /etc/mail/access.db < /etc/mail/access

Below is what my access file currently looks like and can be used as a starting point. All internal addresses have been changed except for spammers!!
