MXguard deployment guide


Step1: tell us the domain name you wish to protect i.e.
tell us the address of your mailserver i.e.
update the MX records for your domain name as follows:

hostname priority result 10 10 10 10 (optional USA DC)

Thats it! once you have completed the 3 steps above, MXguard will be protecting your domain.

Optional Steps

You can also follow these additional steps to further lock down your network, helping defeat spam and further reducing your network's exposure to spam in the process.

Correctly use Sender Policy Framework

MXguard has the ability to interrogate SPF, in simple terms it is a way of telling if the server that sent mail to your server was authorised to do so. Use the free wizard to help you correctly construct an SPF record for your domain name available at We recommend using the
"-ALL" flag at the end which means only servers listed are allowed to send mail on behalf of your domain.

Block Port 25 Outgoing

If you are running a local mail server, only that server should need to commicate with the internet over port 25. It it quite sensible to block port 25 outgoing traffic on your firewall to all traffic inside your network with the exception of your mailserver. In the event that a system on your network is infected by a spambot, it won't be able to send email and this will protect your network from being blacklisted.
