Can't discard spam messages on arrival using Sieve filters

so I think the default behavior is good.

As a default I think so too, but whilst the spam protection in Cloudron is reliable, sometimes the end user wants / needs to be able to filter spam messages directly It would therefore be good to have a simple way of filtering mails to discard spam selectively rather than just having all SPAM go to the SPAM folder. Mails with a SPAMASSASSIN score of over 20, for example, do not need to be saved anywhere, but those with a score of 7 or 8 could in theory be false positives so would warrant 'quarantining' rather than discarding altogether. The same applies to certain sender addresses and subjects.

This does not need to be something defined in webmail clients per domain, but could be a server-wide setting similar to the custom spamassassin rules.

@ccfu yes, I can look into adding customization for spam handling in the coming releases. I have also wanted a user editable whitelist/blacklist for spam (instead of having to rely on admin).

@girish

Sounds good

@girish would it be per-user or per-inbox? I ask since we can have groups using a specific email.

[girish]

@atrilahiji I guess it will have to be per-inbox.

For the original use case of discarding all spam for forwarding mailboxes, this is the default behavior in next release.

Do you mind just expanding on this a bit more? What is a "forwarding mailbox" in your terms? Are you referring to the other feature request I had about mailing lists having an option to not forward messages identified as spam? If so, that's great! But now I will have to go back to the mailing list functionality I had moved away from a couple weeks ago, haha, but that's all good. If I've misunderstood what you mean by "forwarding mailbox" though, please clarify.

@d19dotca sorry, i meant mailing list and not forwarding mailbox!

Any update on this? Ideally it would be nice to be able to define a custom spam assassin rule to instantly discard mails with certain criteria. I see persistent SPAM in the event log with easily identifiable criteria I would like to discard before it hits a mailbox but at the moment all I can do is give it a score of 100 so it is always marked as SPAM.

Whilst we can prevent mailservers with specific IPs or ranges from delivering mails via the firwall, this does not work for hostnames. That would be another way of stopping persistent spamming domains.

@ccfu We have to implement this feature to discard things . Can you raise a feature request there to discuss / with your use case ?
