By the way.. I still dont get it, it is simple when you got a web portal made for you and you just need to input the records, but things are happening in the backend while you do so, thats what I ment when I said I want to do so by myself, without a 'portal' provided to me (as you can see by the wa...

Unless I'm mistaken about what you are doing, the Domain name for the Certificate should be for your hMailServer hostname. Not the Domain names you are hosting on hMailServer. Example if your hMailServer hostname is mail.example.com then this hostname is the name which should be used on the Certifi...

if you comply to the terms you can always use https://freedns.afraid.org/ to get a subdomain from one ot the provided domains
in some domains they let you put in MX records .. and be aware that they have their own definition of public and private domains regarding who can add pointers in them

Hi I am a very new user to this SW, and so I must appologize that my question might be a bit stupid.

The problem I see with this is how many logon connections can you stack? They know there will be a ban or tarpit after x failed logons, so can they stack and try 100 or even 1000 with the limit set to 1? What is the stacking limit? in [Settings][Protocols][SMTP] - General "maximum numer of simultan...

I have enabled autoban to lockout users after a single wrong attempt, but occasionally I am logging up to 10 attempts on the same external IP. It looks like the attempts were simultaneous.

Yes, I’m absolute sure it is no spam

DKIM, IP-address and content are all correct. Only SPF not according to hmail.
