#anti-spam — Public Fediverse posts

We are very close to a new OpenBSD release. "You Have Installed OpenBSD. Now For The Daily Tasks." https://nxdomain.no/~peter/openbsd_installed_now_for_the_daily_tasks.html can help you prepare for the upgrade.

If you are using exim as your MTA (or any other non-base system MTA), "OpenSMTPD Is The Mail Server For The Future" https://nxdomain.no/~peter/time_for_opensmtpd.html contains useful pointers for a better mail future.

Migrating mail servers from exim to OpenSMTPD (smtpd) is fun and useful https://www.undeadly.org/cgi?action=article;sid=20260516064650 #openbsd #opensmtpd #smtpd #exim #email #smtp #mail #spam #antispam #greylisting #greytrapping #mailmigration

OpenSMTPD Is The Mail Server For The Future https://nxdomain.no/~peter/time_for_opensmtpd.html Migrating to OpenSMTPD from exim on OpenBSD was joyfully painless and smooth. #openbsd #opensmtpd #email #smtpd #rspamd #spam #antispam #greylisting #greytrapping #mailserver

Want to Guess How Many Spam Comments We’ve Blocked Since 2016? https://lowendbox.com/blog/want-to-guess-how-many-spam-comments-weve-blocked-since-2016/ #Editorial&News #wordpress #antispam #akismet #Spam

#InstanceAnnouncement Coordinated Potential Bot Network Suspended

We have detected and suspended 5 coordinated bot accounts today.

Indicators of Compromise:

• Content consists of semantically incoherent English text generated by LLM — no direct harm observed, but likely used for account seasoning and filter evasion
• All 5 accounts registered between 2026-03-18 17:52 and 2026-03-19 23:50
• Profiles contain a single English sentence + emoji, or several meaningless English phrases
• All connection IPs belong to Cloudflare proxy ranges
• Registrant domains include disposable email services and high-risk domains

Actions Taken:
Accounts suspended (all IPs verified as Cloudflare IPs — no user privacy has been compromised):
@iwutyp 162.159.XXX.XX
@PhyllisReynolds 172.70.XXX.XXX
@ezob 104.23.XXX.XX
@uhux_xudym 104.23.XXX.XX
@Ethel_Robinson 172.68.XXX.XXX

Email domains blocked:
tmail.lt, maxseeding.vn, dqsbf.blema.io.vn, sphinx.launders.money, kimora.space

Notes:
Registration had previously been set to open in order to simplify the sign-up process. We are now enabling "Require approval" + "Require a reason to join".
If you spot accounts with similar characteristics, or matching email domains/IPs, please report them.
This instance does not welcome malicious or unmoderated bots.

#实例公告 封禁协同潜在的僵尸账户网络

今日检测并封禁了 5 个协同运作的僵尸账户

行为特征：

1. 内容为 LLM 生成的无语义英文词句（虽然目前未做出实质性的危害，但是可能是为了养号，规避审查）
2. 五个账户全部于2026年3月18日 17:52 — 2026年3月19日 23:50注册
3. 账户Profile基本为：一段英文+emoji或者几段无意义英文句子
4. 所有连接 IP 均属 Cloudflare 代理段
5. 注册域名含一次性邮箱服务及高风险域名

已采取的措施：
封禁账户（经核查IP均为Cloudflare IP，未泄露任何用户隐私）：
@iwutyp 162.159.XXX.XX
@PhyllisReynolds 172.70.XXX.XXX
@ezob 104.23.XXX.XX
@uhux_xudym 104.23.XXX.XX
@Ethel_Robinson 172.68.XXX.XXX
封禁邮箱：
tmail.lt、maxseeding.vn、dqsbf.blema.io.vn、sphinx.launders.money、kimora.space

总结：
由于前段时间为了简化注册流程，关闭了人工审核
将开启“注册时需要批准”+“注册时需要提供理由”
如果大家有发现类似行为特征的新账户，相同邮箱域名/IP请谨慎辨别
本实例不欢迎任何恶意/不受管制的机器人注册

It’s The Shit!
Deso pour le blague, c’est l’appli qui redonne l’espoir face a déluge des aides à installation des panneaux solaires. Et quand il y a une apelle qui passe il y a le plaisir de l’ajouter à la liste commune. C’est ça aussi le fraternité. Pour l’anecdote, les combis compatible à box orange possède une blacklist de 30 places, et il faut retaper le numéro à la main après avoir trouvé l’option dans les menus.
N’oubliez pas à soutenir le projet. #antispam

You're welcome. 😁

This is already in place on https://www.qweb.co.uk for testing, and will be rolled out to at least the bigger sites we host imminently.

You can't even tell it's in there, can you? 😏

This was the final jigsaw piece in a whole suite of mechanics I've built to secure our servers from aggressive scrapers. Enormous blog post on it all is incoming. 👍

I added a few more translations of the phrase "The rest is trash" to the spamtraps at https://nxdomain.no/~peter/traplist.shtml (see https://nxdomain.no/~peter/the_rest_is_trash.html or https://bsdly.blogspot.com/2026/02/the-rest-is-trash.html).

If you want further translations added, please let me know (with translation in your message).

"The Rest Is Trash"

We are now halfway through the nineteenth year of greytrapping, still tracking and collecting from the wealth of imbecility out there

Ha sido mencionar Durov lo de Sánchez y ya me ha salido el primer mensaje de Spam en la app en mucho tiempo.
Que se cuide de que empiecen a spamear a los usuarios españoles que le puede salir el tiro por la culata, ya que puedo estar de acuerdo con cosas dichas en su mensaje, pero si empieza a haber Spam la gente puede huir en masa, aunque sea de vuelta a Whatsapp.

Me repito, echadle un vistazo a las distintas apps que hay para XMPP y Chatmail

Reprising my Sunday, Feb 1st post for the midweek crowd:

The Rest Is Trash https://nxdomain.no/~peter/the_rest_is_trash.html (tracked https://bsdly.blogspot.com/2026/02/the-rest-is-trash.html) following up on #greytrapping, updating the 18 years piece https://nxdomain.no/~peter/eighteen_years_of_greytrapping.html #openbsd #spamd #greytrappng #greylisting #antispam #cybercrime #networking #spam

I wonder whether they also believe in the tooth fairy:

Jan 25 07:48:32 skapet spamd[43842]: new entry 111.68.23.116 from <> to <[email protected]>, helo delivery9.nospamcloud.com

Yes, it's a fresh one, see https://nxdomain.no/~peter/twenty-plus_years_on_smtp_callbacks_are_still_pointless.html #smtpcallbacks #antispam #counterproductive #spam #cybercrime

The latest "Lazy reading" by Dragonfly Digest @dragonflydigest https://www.dragonflydigest.com/ has "Eighteen years of Greytrapping" https://nxdomain.no/~peter/eighteen_years_of_greytrapping.html featured. Later this year it will be nineteen years :) (and updates will come) #spamd #spam #openbsd #antispam #greytrapping #greylisting #cybercrime

Heh.

No, I willl not respond to those comments either :D

Somehow, this is still a thing:

Does this mean "Twenty-plus years on, SMTP callbacks are still pointless and need to die" https://nxdomain.no/~peter/twenty-plus_years_on_smtp_callbacks_are_still_pointless.html (tracked https://bsdly.blogspot.com/2017/08/twenty-plus-years-on-smtp-callbacks-are.html) needs an update? #spam #antispam #smtp #smtpcallbacks #cybercrime #snakeoil #scams

Me acaban de hacer una llamada de un numero que no conozco y la iba a pasar por ListaSpam, veo que esta caída voy a probar otras webs similar también caída, miro otra, caída.

Mucha casualidad me parece. Creo que han hecho un ataque DDDOS a estas web para que la gente no las vaya bloqueando
