Firewall / Spamassassin: Automatic list update

[ruihildt]

We were talking with @rmdes about it, it would be the best to have a default updated list you can subscribe to instead of each Cloudron admin going over the same process on their own.

[jdaviescoates]

@ruihildt yeah, it'd be great if Cloudron could just subscribe to these lists for us.

[d19dotca]

@necrevistonnezr Fully support this, this would be awesome. Definitely been looking into this recently and realized there's no way to keep it updated automatically from lists like that in Cloudron. Some ability to enter a URL to subscribe to or even just have a few built-in ones that need to be enabled would be fantastic.

Would love to see this as well. The license of ipdeny is also fairly permissive.

You may NOW re-distribute our zone files and you can freely use our generated IP zone
files in  your commercial or freeware solutions or services, please read our
Copyright policy and please comply with our Usage limits policy. Linkback to our
service is always appreciated and  recommended.

BTW, for mail server, the mail server already uses zen spamhaus. This is enabled by default (and in fact, no way to disable this).

The output from mail-tester.com provides ~20 different RBL/SBL lists to check. Could be useful to integrate if they have an API.

[rmdes]

@girish There is the risk those lists are too broad, I just had to remove taiwan zone because one of our forum users could not access it.

I think if we ever have automatic list update, the source should be a vetted spam ip list not just IP list blocking entire countries..

@girish @nebulon This repo here seems to be interesting to build on this feature request :

Spamassassin lists from Heinlein

I think that this config file is mostly oriented on German email, probably if an incoming email is in Italian or French or English wold be completely useless, this is one of the biggest issue in spam protection and having a 0% ham.

You need custom rules for every language and if you use Rspamd you also need different AI/db for every language.

I don't think so. Looking into their body cf file, you see entries like this, I'd say more than half is English:

@rmdes said in Firewall / Spamassassin: Automatic list update:

source should be a vetted spam ip list

My two cents... Cloudron should not be responsible for vetting the list. It should be (ideally) as simple as admins enabling/disabling lists that are pre-packaged by Cloudron in case they can't just allow any dataset to be used, or we'd be able to throw in our own links to files updated by various vendors such as those from Firehol for example.

I think that's what you meant, but wanted to clarify in case, as I would hate to see Cloudron being responsible for doing any kind of manual vetting, that should definitely be on admins to do. Cloudron just needs to allow access to the lists and we then go from there as admins.

[d19dotca]

There's even a list for Cloudron team to use for this forum haha

https://iplists.firehol.org/?ipset=stopforumspam

Now imagine if that could be used in the firewall automatically. Would be awesome.

[rmdes]

@d19dotca Yes that's what I meant, hence the lists I suggested: https://forum.cloudron.io/post/20010

[rmdes]

The more I read about FireHol the more I wish this was backed into cloudron install directly, it seems to me that Firehol is a great source to rely for blocking bad IP's

[necrevistonnezr]

@girish
Did anything come of this...?

[necrevistonnezr]

Can we re-visit this?

[necrevistonnezr]

I guess since the blocklist is in /home/yellowtent/platformdata/firewall/blocklist.txt, one could build something with a script & cron?

[necrevistonnezr]

@girish is the way I described feasible? Is that txt file the actual list the firewall accesses to check blocked IPs or is this txt file e.g. used to feed into a database?

[girish]

@necrevistonnezr Updating the txt file is not enough. The txt file is actually just a "cache" , the real value is stored in the database.

[necrevistonnezr]

@girish Ok, so simple scripting is out of the question.
