Direct To Mx

• While catchall addresses are a well-intentioned feature (ensuring that any mail directed to a domain can be received and directed to someone in charge, even if the address is misspelled), they cause problems when mixed with spam and other forms of mail abuse.
• Web server logs are usually maintained in a special directory outside those of the website(s) handled by the server.
• Spammers can send such an ndr directly or make a legitimate server send it for them, adding to its credibility.
• Direct-to-MX is a mail-delivery technique used by spammers in which mail is sent directly from the spammer's computer to the recipient's mail exchange (MX) host, bypassing any intermediate mail transfer agents.
• These sites are not necessarily spam sites, but the list is provided so that you may choose not to accept email directly from them.
• Email transmitted directly from a dial-up system -- as opposed through the dial-up system's own provider -- is very likely to be spam.
• A Directory Harvest Attack (DHA) is when a spammer bombards a domain with thousands of generated email addresses in an attempt to collect valid email addresses from an organisation.
• Third, it can cause bounces and complaints to be directed to the innocent third party.
• Some spam is only informational and because there is no direct product for sale, the spammer does not need to leave a website address or phone number, and this makes it harder to track them down.
• The direct-to-mx technique allows message origins to be disguised (although not completely), and keeps the outgoing mail from being monitored or detected by the sending isp's mail system.
