O.k.
Mgb has an sme server in server only mode used for mail proxy and websites hosting , configured with 1 network card.
Until now the server has been working great.
Mgb decided to add another network card to improve performance (nic bonding i think) .
A week after adding the second nic Mgb had a problem with an infected (virus) station that was sending a lot of spam using port 25
To stop the spam sending Mgb blocked port 25 and added smtp authentication inside the network.
The above port blocking and smtp authentication did not help and web surfing has become vary slow .
After checking the server Mgb found out that the server is not blocking port 25 and sending thousands of mails to the administrator .
At some point the mail server stopped working at all and had to be reinstalled.
Mgb has another sme server in a diffrent network configured with nic bonding that is showing the same problems as first server
I mentioned (a lot of log mails to the admin , and later a none working mail server) , this network has been working great for a few
Years with a single network card and Mgb says that it doesn't have any virus infected stations inside the network.
Both servers were replaced and put aside for testing and understanding what happend ( i wish i had a generous boss like that
)
In the second server Each nic has a diffrent ip address eg : 192.168.0.1 and 192.168.0.2
