30 are getting through, but how many are you blocking? If you are only blocking 10 and letting in 30 you need to address it. But if you are blocking 5000 a day and only letting in 30 you are doing about as good as you can.
Do you have your Ironport set up to check RBL's like spamhaus? That is a must, they react much faster than you can. And dig into those IP addresses a little more, are they coming from commercial mailing houses....then you need to block the whole range, not just the single IP addy. From: Fergal O'Connell [mailto:[email protected]] Sent: Wednesday, May 18, 2011 11:03 AM To: MS-Exchange Admin Issues Subject: Unsolicited emails from mailing groups Hi All, Just wondering what you folks do to combat unsolicited emails from Mailing lists. We have Exchange Server 2007 Sp1 with 2 x Clustered C150 Ironport. Our CEO and executives are getting about 30 unsolicited email's a day. At the moment they collect this mail and then hand over to me after about 5-6 weeks for me to deal with. This is what I have don't to try and limit these unsolicited and marketing emails. * On the Ironport device I have tried to block the senders via IP and domain name. * Created a mail flow policy to mark marketing mails and deliver these mails to a separate mailbox via a transport rule. * Exchange transport rule to deliver emails containing certain wording's to a separate mailbox. * Continue to unsubscribe the user from various mail lists. But it appears that I am just going around in circles. The problem is how do I put a stop to this? Any thoughts? The information in this email is confidential and may be legally privileged.
