exchange sending spam
Posted on 2011-02-17
Have a isseu with a SBS2003 server sending spam.
Logs show a external ip sending spam true the server.
pc's connected to domain are scanned and clean, so is the server.
There is a useraccount (only localrihgts, no mailbox etc) without a password which is used for connecting to a shared folder. PC's who use this account are not connected to domail,but the SBS is DNS server for those.
How can I set up a Rule that only the 3 domainusers can send mail and not some script orso
