1. I have an SBG 8.0.3 and an SMS for SMTP 5.01 gateway installed. Most of RDNS failed sender e-mails are going through the gateways. I would like to set up the gateway to filtering out and move to quarantine the RDNS failed e-mail. How to set it up?
2. If the mail HTML formatted and contains only an img src and a href, the dictionary filtering does not working. - Tipically Chinese pharma spams... - Why?
Add. info:
- these emails senders are usually xxx@hotmail.com, or xxx@yahoo.com - I don't want to block all of yahoo mails;
- the sender IP resolvable but RDNS fails, the IP's are tipically changing - probably from DSL pool;
- the body does not contain plain text, only remote images with links;
- standard built-in filtering rules are not filtering out these mails
3. How can I find out a "scanned and quarantined" and "filtered out" message's spam score? The header does not contain this info in the quarantine...
Many thanks
