Requirements

As an ELSE administrator, you must have read The Official X-Itools ELSE 0.9.19 User's HOWTO before to read this one.

To get the best experience with the ELSE, it's strongly recommended to follow the technical and security requirements below.

Technical requirements

Here below are the minimum technical requirements to use the ELSE on a user workstation:

• 3 GHz dual-core CPU
• 4 Gb RAM
• HD screen with resolution of 1920x1200: below this resolution, the Web User Interface cannot be displayed entirely
• Firefox or Chrome Web Browser: ELSE Web User Interface is known to work well with those browsers, Firefox being the fastest compared to Chrome. Use of Internet Explorer is not recommended.
• Network Card with High Bandwidth of 1 Gbits/s

Security requirements

Here below are the minimum security requirements to be checked when using ELSE on a user workstation:

• you MUST check the ELSE make use of HTTPS when accessing its web site. NEVER NEVER use the ELSE if you see the service is provided via HTTP. Because the ELSE is a software that can be seen (and that is) very intrusive in the emails that are processed by it, the information it handles are very sensitive. All those data related to email contents must not be manipulated if the ELSE is running on a web server that's not encrypting communication using HTTPS.
• If you've to go away from your workstation, even if it's just for 2 minutes, then lock-it.

User's skills

As an ELSE administrator, you need to own a solid background in the field of messaging services, messaging protocols (SMTP, IMAP4, ...) and more generally speaking in systems, networks and security.

Extended knowledge in particular with Firewalls, Postfix, Postfix Policy Servers, Microsoft Exchange Server, DNS, SNMP, RSYSLOG, RSYSLOG Windows Agent, PostgreSQL databases, scripting, Apache HTTPD, PHP, javascript and so on, is of course a must have.

And finally, some internet related RFCs should have no secrets for you, like RFC821, RFC822, RFC4408, ...
