I bought a phone number on crypton.sh and attempted to use it for verification, I haven't got any of the codes. I've also tried messaging the number I was given but it fails to go through it's not even active. I messaged their support just over a week ago and have essentially been ignored. Just letting everyone know incase anyone has any intention of using them. Source: 12 months ago

Crypton.sh. Mostly UK phone numbers but they are testing other European phone numbers. Uses actual numbers associated to SIM cards connected to a cellular network, so even sites that won't verify against VOIP numbers will verify with their numbers. Also, incredibly private. You can access the site via TOR if you want (including logging into your account to get messages) and pay with anonymous cryptocurrencies. Source: about 1 year ago

Rspamd is the same idea. ASSP is highly configurable and a proxy. Source: 10 months ago

I'm currently looking into using a Bayesian spam filter like Bogofilter or Apache Spamassassin to help out. I'd run the contents of my Contact Us form through the filter after the initial validation, and if the contents are below my spam threshold, I would actually send out the contact us request.

A score below -5 is considered spam. -0.1 DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid This rule is automatically applied if your email contains a DKIM signature but other positive rules will also be added if your DKIM signature is valid. See immediately below. 0.1 DKIM_VALID Message has at least one valid DKIM or DK... Source: over 2 years ago

To detect whether incoming emails are malicious, mail servers also use spam scanners, such as Apache's popular SpamAssasin. The internal workings of these spam scanners can be somewhat complicated (involving Naive Bayes Classifiers on trained, large datasets, for the curious), but the primary takeaway is that these classification systems typically assign a numerical point value to an incoming email to determine... - Source: dev.to / almost 3 years ago
