OPS535 A2 201603
- This assignment worth 15% of your final grade.
- Important: You must be in the Lab on the due date to present your systems in order to have your assignment marked unless it is for medical reason.
Setup an Internet email system for your assigned DNS Domain using the Virtual Machines in your Virtual Network. Your Internet email system must provide the following functions:
- A SMTP email server (running postfix) that is capable of receiving and sending emails for users in your domain.
- Users in your domain must be able to send emails to users in the same domain and users in other students' domains in the class.
- Users in your domain must be able to receive emails from other email users (both in your domain and from other domains).
- An IMAP Access Agent (running dovecot) allowing users in your domain to remotely access their mail.
- Users in your domain must be able to access/manage their mail box using IMAP(s) clients.
- You email server must be configured to check the SPF (sender policy framework) of other domains for incoming email and reject emails that are violating the sender policy.
- Configure your DNS server to implement and provide the SPF protection for your assignment domain.
- Configure your DNS server to implement and provide the DNSSEC records for your assignment domain.
- Provide the administrator for the .ops domain (your professor) with a copy of the DS key for your assignment domain. If you have not already done so, include the glue record as well.
- Configure a DNSSEC Trust Anchor so that your co-nfs server considers the .ops server to already be authenticated. I will provide the key necessary for this through blackboard.
You need the following services and network infrastructure to support your Internet Email System (some of which should have been configured in assignment 1):
- Pri-dns must be the primary DNS name server for your assignment domain with the proper MX record(s), SPF record(s), A record(s), and PTR record(s). It must be queriable by any machine.
- Provide the administrator of the .ops domain (your professor) with glue records for your domain.
- Co-nfs must be a caching DNS server, accessible to machines in your networks, that will forward traffic to the server for the ops domain (172.16.19.1), then to your rns-ldap.
- Rns-ldap must be a forwarding server only.
- It must only be queriable by your co-nfs.
- It must have a copy of the root-hints zone.
- Proper static network routes to and from other Email servers in the Lab.
On the due date you will be tasked to:
- Add two new email users to your domain. Name of the new users will be given in class.
- send an email by one of the new email users to the other new email user in your own domain.
- send an email by one of the new email users to a designated user of other domain.
- receive the reply email from the designated user of the other domain.
- query a record from another domain
- query a record from another domain with dnssec information included.
I will post a script to blackboard that will capture your configuration and logs. You will run this script on your machines and upload the output to blackboard.
If you have any questions or need any clarification, please email your instructor at least one week before the posted due date.
