We push all our outgoing mail from hosting servers through one of our mail gateways using sendmail's smarthost config. In sendmail.mc: define(`SMART_HOST',`smtp.your.provider') This has several big benefits: 1. We can keep an eye on what hosting customers are sending, whitelisting them as appropriate, and help them with any legit issues they have with mass mailing (double opt in list mail ONLY!). 2. The hosting server doesn't have to do the work scanning the mail since the gateway box runs MailScanner/SA/ClamAV, etc. 3. Any spammer, who finds the latest header injection hole in some php script is quickly identified, since a milter or SpamAssassin usually finds such mail quickly - we watch the logs and notify with Nagios of any serious issue. 4. Also, you can block port 25 outgoing (and other outgoing ports as appropriate) to anything BUT the mail gateway, so no smtp engines on the web server are permitted. As a side note, I'd recommend also monitoring your IP space for any RBL listings, setting up TOS feedback loops with AOL, etc... All part of the hosting business these days..
