Excessive Spam

Our Internet provider’s servers recently went down. It has been back up for several days now. Before the service went down we had very little spam. Since it has come back up we are having excessive amounts of spam. One user has up to 500 a day. I contacted them and they said their firewall was back up and functioning, that something must have got into our Exchange Server. I have ran a scan on the server and found nothing. What could have got in to our server? I think it is on their end.

Thank you

It sounds like its at thier end and they have got a issue they are trying to deflect. However you can always check a few things.
1st are you using Exchange with direct delivery to SMTP or a POP3 collector from your service provider?

What kind of Firewall do they have? Most of the firewall do the basic task of blocking and unblocking ports and Ip addresses.

Is the ISP Firewall capable of filtering the spam emails from the genuine one? Could you check with them if they have replaced the old firewall with new one or if is it the same Firewall?
