Spam is always rejected?

Hello,


I can't figure out how to stop Mailbox from rejecting suspected spam messages.


Under Settings > Mailbox.org > Settings spamprotection > Spam e-mails I set "Flag & redirect to: Junk", instead of Reject. However, as far as I can tell, messages suspected to be spam are still being bounced.


  1. Recipient address rejected: Mail appeared
  2. to be SPAM or forged. Ask your Mail/DNS-Administrator to correct HELO and
  3. DNS MX settings or to get removed from DNSBLs; in multi.surbl.org (in reply
  4. to RCPT TO command)


Is there something I'm missing? Thanks!

The option "flag&redirect" instead of "reject" is as far as i know only for the content-filter.

Try to disable RBL (Blacklist) in spam-settings , because I think, "surbl" is a blacklist.


By the way:

I don't recommend such settings. If the sender is listed on RBLs, the sender is the problem, and not mailbox.org. If the sender is listed on RBLs, he will have problems with every recipient worldwide, not only mailbox.org.

Mailbox.org recommends only to disable the smtp-plausibility check if you have problems with rejected mails. To disable RBL is no good idea. In my personal opinion, if there is only very very few spam in the inbox, you could lower the risk of fals positives by setting the content-filter from normal to lenient. But this has nothing to do with RBLs.

For the most cases, the default settings are the best.

Thanks for the good answer.


In this case the "smtp-plausibility" filter is the reason for the block of gandi (this check also does some RBL-checks). So tga schould disable (only) this one.

Thank you for both answers, done, and mail is coming in!


The wording on that settings page could be better, it literally says "spam emails are redirected and not rejected", it wasn't immediately clear that only applies to the content filter.


Indeed, my issue was with _all_ my mail coming through a forwarder (Gandi, with issues, apparently) so I don't get many choices there, I'll disable anything to get my email working again.


Generally speaking, unless the volume of spam is overwhelming, and threatening the quota, I always prefer to have access to flagged messages in a folder so I could check for issues, vs potentially many messages being silently bounced.

What do you mean with "forwarder" and "Gandi"? If you have your own domain, you can use mailbox.org for mail-traffic directly. You don't need a mail-forwarder.

Use your own domain

You just have to change the MX-records. If you are familiar with DNS-settings, that's no problem.

The background is: the spamfilter of mailbox.org works best without mail-forwarder.

Gandi.net is a domain registrar and service provider. When you register a domain with them, they will also host or forward mail for that domain -- without a limit to the number of aliases. The smallest Mailbox plan is limited to 3 aliases, and I need more, so I forward my mail through Gandi and then over to a single mailbox here.

Ich habe in der Fritzbox einen Mailaccount hinterlegt (Variomedia) der an MBO weitergeleitet wird. Ich bekomme dann aus der FritzBox herraus Infos über neue Anrufe etc. Komischerweise kommt genau dieser Fehler seit heute Nacht wenn die FritzBox mir eine Info schicken will. Sonst ging es immer.

Das Problem habe ich auch seit zwei Tagen. Manchmal funktioniert es, manchmal nicht.

Bei der Fritzbox auch? Also scheint es doch ein MBO Thema zu sein. Wie ich oben gesagt habe, kann kann ja nicht plötzlich eine Hand voll Provider die Einstellungen geändert haben.

Unter anderem auch bei den Mails meiner Fritzbox, aber es haben sich auch externe Absender beklagt, dass sie ihre Nachricht als unzustellbar zurückerhalten.

Und die Lösung/Workaround von Peer funktioniert nicht? Vielleicht sollte multi.surbl.org temporär deaktiviert bzw. das Scoring angepasst werden?

My issue was not with the blacklist, but with the SMTP server check. Setting all spam settings to "No" should stop the bounces -- but will obviously expose you to more spam.

I do question the fact that your problem is unique. Obviously some customers, including me, do have similar problems. I would not like to solve that problem by turing off a spamfilter. It did never happen before with my e-mail adress / provider.

All I can say is how I got around the issue for the moment. The rest is up to Mailbox. Luckily, it looks like Peer knows what's going on, so I hope for a permanent solution soon. In the mean time, personally I don't mind disabling all server-side spam protection.

We applied a patch/fix against some effects coming from RBLs. Problem should be fixed. At the end this was a side-effect due to some heavy patching and upgrading caused by Spectre/Meltdown where working mailbox.org config was replaced by faulty default configs coming from the linux distribution companies.


Sorry. Due to heavy and many parallel upgrades at the weekend we missed a QA control here.

Betrifft das Umleiten der Mails in einen Bestimmten Ordner echt nur den Contentfilter? Also nicht auch den SMTP Check?? Ich hatte gestern so ne klassische Nigeria Connection Mail im Spam Ordner. Diese Art wären dann die Mails die statt Rejected in einen anderen Ordner einsortiert werden? Finde ich komisch. Warum geht das nicht bei allen Inhaltsspamfilter,

Realtime Blacklists (RBL) & SMTP-Plausibilitätscheck?

Wir haben eben einen Fix gegen eine von uns verwendete RBL-Liste eingespielt, was das Problem beheben sollte.
