Trouble Sending Email When Offsite?

If you are offsite and unable to send email using the Lab’s offsite outgoing mail server, smtp2.lbl.gov, you may have been blocked by a local Internet Service Provider (ISP). ISPs block connections to outgoing mail servers that are not owned by the ISP. An increasing number of ISPs (like SBC, Earthlink, Comcast) are doing this to help stop viruses from sending email out once they've infected a computer on the ISP's network. Read more.

Spam, Spam and More Spam

Spam is now so commonplace many users consider it a fact of life. A study conducted last summer showed that on a single day in August, nearly 90 percent of all Internet traffic consisted of spam. Anti-spam legislation in the U.S., the CAN-SPAM Act, prohibits sending bulk email and prescribes penalties for doing so. But this act does virtually nothing to deter spammers residing outside of the U.S. Read more.

Beware of the latest Internet security threat: email messages that appear to be Web postcards.

Computing image

U.S. consumers lost $2.4 billion last year to online scammers and phishing attacks. Most fraud was carried out by people gaining access to account numbers and passwords. Phishing attacks send consumers emails which look like they’re from trusted financial institutions. Users are directed to a phony website, and are lured into entering user names and passwords. The collected identities are then defrauded. Delete any messages of this nature, and avoid forwarding on. Go here for details.
