  • Ok, I've migrated email to selfhosted
    Spamassassin or rspamd or ASSP. All very good. Spamassassin just works, but you need to feed it a good cohort of spam and ham (about 1000 messages each). Most people only send it the spam which will then bias it quite a bit and not have it classify spam as spam unless it's the worst of the bunch. Spamassassin is a filter for your mail server.

  • Using Flask for a personal website - add dynamic component?
    I'm currently looking into using a Bayesian spam filter like Bogofilter or Apache Spamassassin to help out.

  • Email send error javax.crypto.BadPaddingException: pad block corrupted
    I've rebooted quite a few times. Updated the app too. I don't use a VPN. I installed k9-mail to test and that works without problems. https://github.com/k9mail/k-9. Source: over 2 years ago
  • Gmail App Alternative focused on privacy?
    On Android the usual recommendations are FairEmail or K-9 Mail. Both are fully open source and privacy focused, it basically comes down to your personal preference. For them to work with your Google Account you will probably have to create an app password. Source: about 3 years ago
