What is spam?
Spam is unsolicited e-mail usually sent to a large number of people that usually tries to sell something or get people involved in some sort of scam. As the Internet grows, so does the problem of spam. More and more people are getting more of these spam e-mailings. For this reason, the Lab is taking steps to reduce the amount of spam we receive.
How well does the service work?
The Berkeley Lab anti-spam solution is doing an excellent job of correctly identify the majority of incoming junk mail. Of course, no system is perfect, so it will certainly miss some spam, and incorrectly identity as spam some legitimate mail as spam. Our anti-spam service has a very low false positive rate -- the number of messages it incorrectly identifies as spam -- may be in the range of 1/100,000.
Please refer to the questions above for how to report junk and false positives. Your feedback will help improve the service!
How Can I Reduce the amount of spam I receive?
- Protect your e-mail address.
To reduce or prevent spam to your email address, try not to give out your email address (via news postings for example) to anyone you don't know.
- Don't Comply with Instructions in Spam Messages
Some spam messages include instructions for supposedly removing your address from mailing lists, thus by all appearances stopping spam from that spam source. However, if you follow the instructions, chances are you are only making matters worse. Many if not most spammers use the replies to confirm addresses and identities of people who will afterwards receive even more spam. If you get spam, your best bet is to follow the procedures described in this page.
- Note that spammers often send spam using blind-carbon-copies (bcc), a method to conceal the addressees by hiding the "To:" address.
- For LBNL users ONLY: Use your lab-standard email address [email protected]
Since LBNL lab-standard email addresses of the form \[email protected]\ are protected by the lab's spam-protection and virus-protection software, we recommend that you set your From: and Reply-To: addresses in your email client and any web pages to \[email protected]\ address
Legitimate companies in fact do unsubscribe as promised and we have often used such unsubscribe links with legitimate companies with good results.
These are companies whose emails to the user "make sense" because the user did business with them, e.g., bought something from them or corresponded with them.
Illegitimate companies use the unsubscribe information to confirm your address is valid. Since it is hard to know who is a criminal, if in doubt, not unsubscribe.

sendmail anti-spam rules
The lab maintains a small set of server-side filters to block long-term, high volume abusers of our system.
Third Party Relay
A major contributing factor to the spam problem is the ability for spammers to relay their e-mail through third party servers, making it difficult to track it back to the originator. This is called "third-party relay."
For more information on why we need to block this kind of relaying, see this webpage entitled "What is Third-Party Mail Relay?"
Therefore, the Lab does not permit "third-party relay." Mail that comes into our server from outside the Lab that is also addressed only to addresses outside the Lab is rejected.|
Sender Address Checking
A hallmark of spam is that the sender address (the "From:" address) is often not valid, since spammers generally don't want you to be able to respond to the message. So, the sender address on all messages is now checked to make sure it at least refers to a real computer on the Internet.
