Hi,

I've receive an email from trendmicro regarding Hosted Email Security (HES) Notification, asking to:

«Configure your firewall to accept emails from the following IP address range of our mail server so that Trend Micro Hosted Email Security service can deliver email to your business.

You may already have these configured:

•         216.104.20.0/24

•         216.104.4.0/24

•         150.70.149.32/27

 

You must add these:

•         150.70.224.0/20

•         150.70.160.0/20

•         150.70.176.0/20
More information is also available http://esupport.trendmicro.com/Pages/How-to-accept-emails-coming-from-Hosted-Email-Security-servers-only.aspx

What it's necessary configure on ISA server, which is my firewall?

Create new computer objects - one for each of the IP address ranges mentioned above.
Edit your server publishing rule that allows smtp traffic inbound and change the All Users section to just include the new computer objects you have created.

By the sound of it you will need six computer objects.

Just bear in mind that this will take effect immediately and this will mean that port 25 traffic will ONLY be accepted from these mail servers so make sure your external dns MX records ARE pointing at Trend servers....

In this case this is necessary, because we have our mail hosted in other ISP, and for now we don't wan't to change for another.

Thanks.
