Hi,
We have just been used as a smtp relay for one of the US spam companies and it crashed one of our mail servers, the service remained unaffected as our backup systems took over but we use sendmail and I cannot seem to find out how to stop us from being used in this fashion.
I know this is not the correct list for this sort of thing but I need some expert advice as our software suppliers don't know how to stop it.
As a general warning to everyone out there we need to protect our systems from these people who are starting to use us all to deliver their mail for them without paying us a penny.
Please someone help,
Set up an access list in your main router and block incoming smpt traffic for the entire net-address of this company or for the mailservers they own. -- Med vennlig hilsen / Kind regards Stig Bull IP-drift Telenor Nextel AS email privat: stig@undernet.org email jobb: sb@online.no Tlf sentralbord: 22 77 19 00
