hello

we buy a barracuda spam & antivirus 400 series and Top Spam Recipients Report show info like this:
1. somedomain1.com[200.24.xxx.xxx] 77
2. somedomain2.com[198.1.xxx.xxx] 30
3. unknown[195.55.xxx.xxx] 27
4. somedomain3.com[190.90.xxx.xxx] 26
5. somedomain4.com[64.95.xxx.xxx] 21
6. unknown[37.215.xxx.xxx] 20
7. somedomain5.com[178.89.xxx.xxx] 14
8. somedomain6.com[66.197.xxx.xxx] 14
9. somedomain7.com[208.82.xxx.xxx] 14
10. somedomain8.com[174.37.xxx.xxx] 14


by default the only server to have permision to send mail is located in the LAN and it isn't show in the table, the other domains correspond a hacking? or i have a problem with the configuration of barracuda system?.


thanks for your help.

Jaime,

That looks like a Top Spam Senders report. When a sender is blocked their source IP increments one since the last report. If you search the message log for items with reason AUTH you will see failed SMTP login attempts if there are any.

I hope that helps,
Justin
