'''Spam''' are the bad effects of unsolicited or void messages. There is risk of abuse, fraud, or phishing.
== Indications ==
* Unknown or strange domains
* Unexpected e-mails from abroad
* Unrelated e-mail domains, not corresponding to the "sender label"
* Multiple e-mails the same day from the same domain, possibly using different, or "random" usernames
* Messages about expired accounts, domains, credentials, card readers, tax returns, investments
* Suffix usernames
* Foreign domains for domestic institutions or companies, e.g. FOD (Federale overheidsdienst)
* Unexpected e-mails from the bank
* Exotic financial transactions: legacies, lotteries, emergencies
* Exotic law firms
* UPPERCASE text, uppercase sender addresses
* About "hot" techniques, like solar cells, crypto currency
* Fake e-mails gimmicking official corporate style
* Using the RE: subject prefix (to suggest some previous communication)
* Unsollicited, unexpected, or unrelated procurement
* Non-conventional style
== Counter measures ==
* Block unwanted top domains (country codes).
* Block unwanted language codes (only accept regular language codes).
* Block unwanted senders, or domains.
* Inspect URL links before clicking; suspect random URLs not corresponding to corporate [[Internet domain|internet domains]]. Instead use your own "bookmark" links.
* Be very careful if the message is too good to be real.
* Send fake messages to e.g. [mailto:Verdacht@safeonweb.be verdacht@safeonweb.be]
