Can you confirm that the database is accessible using a MySql administrator such as MySQL Workbench?

You can also try a telnet to the address and port of Mysql where you should get an answer

Re: DNS

I reaffirm, with that price you can get a CISCO router for example. In that list there are very few teams and brands compared to the total. It is anecdotal.

I will enter amazon and look for the words CISCO and router. I am sure that any router in that price range is not easily vulnerable.

Re: DNS

I have been using HMailserver for years on a VPS server without a local DNS. I use the DNS server of my domain registrar. On another server located in my office I use local DNS. I think that before deciding whether or not to use a local DNS server, other questions should be asked. Will Hmailserver b...

Re: Not receiving mail

I would start with the simplest:
- Is it the same IP address?

- Can you make a telnet connection to port 25?
It is common for hosting providers to disable port 25.

Use this diagnostic tool.

Re: Mail blocked by Spamhaus

I think it refers to the inverse resolution of the DNS, except for some cloud services, if you use a physical server on a fixed ip, you must request your internet provider to associate your ip with a name in such a way that:

1.1.1.1 = mail.domain.com
and
mail.domain.com = 1.1.1.1
