I've noticed that the spam filtering in Thunderbird Mail, which has previously been amazingly good at distinguishing legitimate emails from spam, has recently started flagging quite a few legitimate emails as spam.

Is that just me or has anyone else noticed it?

Right, that's it - litestream.io is being to flaky. It's time to migrate my #email server from #sqlite to #PostgreSQL. Pray for me. #selfhosting

Quick question for the infosec community: what email encryption standard do you recommend in 2026?

I have been comparing X25519 (Curve25519) vs RSA for key exchange. X25519 is ~500x faster for key generation with 32-byte keys vs 256+ for RSA.

Anyone using ECIES pattern (X25519 + HKDF + AES-256-GCM) in production?

Alright #Betterbird and #Zoho users. Running into an issue where when I send an email from BetterBird, it seems to be sending twice. When I look at the email threads on the Zoho app on iOS, it shows two sent messages at the same time instead of one.

What settings should I look into to find out what’s doing this?

As someone in infosec, how do you handle your personal email?

I got tired of Gmail reading everything, so I built a self-hosted
alternative with:
- X25519 + AES-256-GCM encryption
- Postfix/Dovecot on a French VPS
- SPF/DKIM/DMARC + fail2ban
- An AI cockpit that classifies urgent vs noise

Curious what setups other infosec people use. ProtonMail?
Self-hosted? Something else?

I've been spending a bit more time dealing with my self-hosted email server and its spam load. The attached article was a fun reminder that so much of our ecosystem of being abused by randos on the net is caused by email addresses that are not only long-lived, but also easy to scrape.

Do you get a lot of spam?

I'm genuinely surprised when some people say they get multiple email spam EVERY DAY, whereas I may get 1 or 2 PER WEEK. Is it because I've always been careful where I use my email address or because I don't have an easy-to-guess email address?

What about you?

I very rarely get any spam emails

I am learning email sieve programming to protect my sanity. Turns out, there is an entire programming language dedicated to filtering incoming emails.

Since I use Proton Mail, I thought I could test their Lumo LLM chatbot to see if it can help at building Sieve filters. It failed. From the beginning, it assumed tags and folders were different things, and insisted I use tag "Priority High"; to mark important and urgent stuff high priority. Rookie mistake!

In case you didn't know, emails started out as basic text files people send to each other on the same mainframe. Email recipients can store those .eml files however they would like. Sieve language never differentiated "folders", "tags", "categories" etc. All those things are actually just labels that insists to act differently. They all use fileinto expression. For instance, you want to tag a utility bill email as ToDo, and also move it into "Bills" folder,require "fileinto"; if address :matches "From" "@utilitycompany.com" { fileinto "ToDo"; fileinto "Bills"; }
