Hi all,

 

I am getting thousands of these portscans (Below are 3 examples) They are
basically all from my exchange server to different IP addresses mainly on
port 25 I have noticed a few of 53 too.  They are all going to addresses on
the internet and I am not sure if I should be concerned or not, they are
happening continuously all through the day. 

 

If I can offer any more information please let me know, I would really like
to get to the bottom of this, I have googled away and find similar posts but
no answers.

 

When I click on the link to Snort it says 


GEN:SID 

1:27 


Message 

Sorry, no such sid-gen (1:27) 

 

 

Any help greatly appreciated.
