I have hMailServer set up on my windows server 2008 machine.
I just started noticing in the logs that there are a lot of entries related to people trying to send external to external mails (obv spam?) through my machine.
I've not set the server to allow ext 2 ext mail delivery. It did look like it was all coming from one ip range but now it's from all over - is there anything I can do to stop this?
The ip ranges seem to be in the same range but it's only the first byte that's the same - it comes from 2 ranges by the looks of it - i'm not at my server but it looked like 114...* and 214...*
Might be wrong with those but you get my meaning. I was looking at using IP Security Manager to stop those IPs even hitting the mail server
is that advisable? being that they are such huge ranges?
If it is advisable - how do you specify a range in the ip security snap in?
