False positive on SpamHaus
-
SpamHaus connections from Cloudron are not at all reliable at the moment. As @girish wrote, something seems to have changed recently at SpamHaus.
There are two issues that would appear to both be caused by the same problem (refused connections to the SpamHaus servers): the false positive reports that the IP is on the blocklist and the lack of blocklist checking of incoming mails resulting in mails from IPs that are on the blocklist not being identified as such. That could explain an increase in the amount spam getting through, though SpamAssassin rules should still filter a lot of these. SpamAssassin cannot delete incoming mails but can at least make sure they go straight to the Spam folder.
There are other blocklists for incoming mail. I have had good results with Abusix, for example. It is not possible to set a different blocklist in the mail configuration checks though.

@ccfu I exactly followed your advice: removed SpamHaus and added SpamAssassin rules https://forum.cloudron.io/post/105256 by @d19dotca

We really need some more insights about this issue since reproduction is very hard to impossible.
Disclaimer If you are not comfortable posting your details here, I just enabled that everyone in the forum can send me private messages.
Anything not related to this topic in my private messages will be ignored.
To everyone affected, please provide us with the output of the following command from your Cloudron server:
cloudron-support --send-diagnosticsAdding to that, we could need the domain that you are using for mail.
Furthermore, the more detailed you can describe your system and how you use it, the better we can try to reproduce this to find a solution. -
I removed SpamHaus form Mail ACL list and system continue giving "Email is not configured properly"...

@p44 Removing the entry there only stops IP addresses of incoming mail from being checked against the blocklist. It does not affect the email configuration checks, and there is apparrently no way to override this at the moment.

@james, I sent you details via chat yesterday. Or did you mean something else by "private message"?

I just noticed that my Cloudron instance is experiencing similar symptoms: my Email status settings says that my IP is blocked by SpamHaus Zen, but when I put my IP into SpamHaus Zen's checker it comes up clean.
It's a bit unclear at the moment if there is a resolution to this or not?

@thetomester13 are you on a vps or personal cloud?

Hello @thetomester13 please read the post I've made here => https://forum.cloudron.io/post/107766

After several years running Cloudron, this issue made me shut down my server and find another hosting for my needs. I have had several issues in the past, and the support team was always willing to help, and I am very thankful for that. But this Spamhaus problem affected my private and business communication for several weeks with no foreseeable solution. I believe that I will use Cloudron for some less critical applications in the future.

This kind of situation clearly worries me about hosting my email on Cloudron and is the kind of concern I had expressed few weeks ago to people hosting their email on Cloudron. Ref: https://forum.cloudron.io/post/107104
And just when I started to be less worried, this SpamHaus issue popping up and being such a blocker is quite concerning
-
@neki If you are experiencing problems with inbound mail being rejected, have you tried just removing Spamhaus from the list of DNSBL checks?
@ccfu No, I haven't tried removing Spamhaus from the list of DNSBL checks. However, I don't think it would help in my case. My IP address wasn't listed in Spamhaus, and the issue seemed to be related to a misconfiguration warning in Cloudron, even though everything was set up correctly. So I doubt that disabling Spamhaus would have made a difference.

Not sure why ... maybe it affects only a few users and they do not use their email servers for important stuff, I don't really know. To me, it was a nightmare knowing that some messages for me were not delivered (not even to the spam folder).
