How the spam filter works and what you can do to prevent spam.

What is spam?

Spam or junk is the name given to unsolicited e-mail often from untrustworthy sources. As the provider of, Swisscom has a legal obligation, pursuant to the Swiss law on telecommunications (Art 83 FDV), to protect its customers from unsolicited mass advertising to the extent permitted by the latest technology. It uses a spam filter for this purpose.

How the spam filter works

The spam filter systematically checks all inbound and outbound e-mails for typical spam elements, such as links that are classed as unsolicited by recipients and therefore flagged as spam. All suspicious e-mails are sent to the spam folder. The spam filter also responds to global spam messages. In other words, if a large number of recipients flag an e-mail as spam, it will, in the future, be sent to the spam folder.

Report spam

If you receive a spam e-mail, you can flag it as spam to the provider of your e-mail service.

In Bluewin, you do this by selecting the icon in the top centre of your webmail.

However, please ensure that the mail in question really is unsolicited spam and not a regular newsletter. Otherwise, mail from genuine senders will, in the future, be diverted to other people's spam folders.

To stop receiving a regular newsletter, simply click the unsubscribe link at the foot of the e-mail.

Previously, a spam e-mail would be easy to identify from the many grammatical errors. This is no longer the case however. Nowadays, senders will often use the names of big companies and also copy their e-mail layouts. Follow the tips below to reduce your vulnerability to spam.
