As for phone numbers, I’ve used MySudo before and it works perfectly – https://mysudo.com/. Source: about 1 year ago

Thanks for the love u/maimonides! We recommend a PO Box (or CMRA/PMB), masked email addresses, and maybe even a VoIP phone number (MySudo is a simple and low cost option, $10 a year for one phone number) when having to give out your personal information. We have a blog post about using alias information, obviously something like this would have to be in your real name, but your Netflix account and lots of other... Source: about 1 year ago

If you did want to go down the alise route try https://mysudo.com/ You can set up multiple emails with multiple aliases and categorise them. You can set up virtual cards with this service as well. Source: about 1 year ago

If you want security: a phone with GrapheneOS installed, an always on vpn such as PIA VPN or Proton VPN, communication through secure end to end encrypted messengers such as signal, session, etc... And anonymous mobile data (there are a handful of data only esim providers that allow anonymous payment), I use INVISIV PGPP, not sure what's available in your country, as well as a voip phone number such as MySudo.

Rspamd is the same idea. ASSP is highly configurable and a proxy. Source: 12 months ago

The famous spam filter SpamAssassin. Score: -0.6. 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: almost 3 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 / about 3 years ago
