Ms Exchange - Symantec Mail SEcurity - RBL
Posted on 2005-05-17
I currently use : Microsoft Windows 2003 Server with active directory, Microsoft Exchange 2003, Symantec Mail Security (latest version upgraded last week)
I have received a lot of complaints from the management where I work concerning spam. I know we all receive a lot of spam and I told them about purchasing a physical mail firewall or a competent spam filter software, but I cannot get the budget unlocked for this.
Since I have to work my way through this, I tought of looking at my SYmantec Mail Security and finding some way to block spam. I looked at the heuristic engine but it randomly blocks everything and it is not working too well. I then found the RBL or IP4R as they call it.
From what I have read it seems good but I have two problems with that :
1. Finding a good free rbl server that will not block good mail
2. Symantec Mail Security has now way to log rejected mail, it simply blocks it and sends it back, which could lead to blocking good mail and not knowing about it.
What should I do about those two things ?
