    Input Hardening Plesk with AbuseIPDB

    Many thanks @Kaspar for your time, thoughts and advice :) Yes, I get that fail2ban is dynamic and have that locked down (maxretry = 3) to help limit things, but there is also the fail2ban 'plesk-permanent-ban' jail, although that is an all ports, TCP and UDP total ban, but you could create...

    Input Hardening Plesk with AbuseIPDB

    I am looking to remove some of the noise and brute force attempt from the maillog and would appreciate people's thoughts and experience. There seem to be three options: 1. The Plesk firewall 2. Fail2ban 3. AbuseIPDB Plesk firewall The firewall (iptables) allows me to be specific and so I...

    Resolved Lots of DKIM/DMARC errors - mails are rejected

    @TorbHo, set your DMARC policy to none or quarantine, then send a message to another mail service (which should be delivered with a DMARC policy of 'none') and inspect the header. As @Sebahat.hadzhi said, you likly have a domain conformance failure, probably due to you setting the 5322.From...

    Issue Mail delivery deferred (4.4.2 delivery temporarily suspended)

    Ah ... I knoew it. As soon as I post, I'll find the fix... I recall in the rapid migration, SpamAssin is no longer availe and I presume has been incorporated into Plesk Email security. I therefore looked at Warden Anti-spam and Virus Protection, but didn't go through with licensing it. All has...

    Question Renewing Let's encrypt automatically

    I can confirm, cert rotation with wildcard deselected now goes not only without challenge, but oh so quickly. You have just saved me a bunch of time. Thank you so much @Kaspar :cool:

    Question Renewing Let's encrypt automatically

    Hi @Kaspar ... so it is the wildcard option that triggers the _acme.challenge update at every cert rotation? If that's the case, it will save me a lot of hassle. Plesk/SSL It! like to 'encourage' including the wildcard option, but if ignoring this removes the need for TXT record update each...

    Issue Let's Encrypt "urn:ietf:params:acme:error:caa" 403 failure

    I have been trying all manner of things @mow :) What's more, I have some interesting findings and questions for Plesk... I have indeed set CAA for the various domains, however, and yes as a CISO I recognise you 'best practice' point, CAA are not required and both these 'problem subscriptions'...

    Issue Let's Encrypt "urn:ietf:params:acme:error:caa" 403 failure

    This issue is back and looking for anyone reporting this issue I find my own post :rolleyes: What I notice is that I mention two subscriptions having this 'checking CAA' error ... both for domains that have no CAA and never have. I also see I said... Well, the same 1+5 subscription is back to...

    Issue Let's Encrypt "urn:ietf:params:acme:error:caa" 403 failure

    Just to add to the thread, but not expecting a magic answer, other subscriptions on the same host all update okay, even now, one that was suffering the same 'urn:ietf:params:acme:error:caa' 403 error. Trying to work out what is the key issue, although I cannot see why one that was failing, is...

    Issue Let's Encrypt "urn:ietf:params:acme:error:caa" 403 failure

    Many thanks Peter. Yes, I understand a 403, but it's not just "can't access", but is being forbidden .. it's a 403, not a 404. I'll have a look at the logs and maybe put a tail on while an attempt to reissue is running in the hope of seeing what it is that's being attempted and denied.

    Issue Let's Encrypt "urn:ietf:params:acme:error:caa" 403 failure

    Hi Peter, no, nothing in front and Nginx disabled just to rule that out. No, DNS is not managed by the Plesk service and yes I know where the autorotative DNS are and it all been working for years. Yes I have checked the DNS for all names and one idea I followed was a misreading of an wildcard...

    Issue Let's Encrypt "urn:ietf:params:acme:error:caa" 403 failure

    Just to add to my own thread... I took the smaller 1 + 5 domain subscription I de-selected all the additional domains and tried again ... it still failed I then de-selected wildcard and when to domain and www.domain options only ... it worked! ... however... While the 'domain + www only' v...
