ShopaholicQ: I have AcumbaMail as one of the outbound smtp.
In your gateway options, does it allowed to connect to a third party that is not listed? I see you have Amazon SES and others.
Is there any type of firewall protection on both the backend, as well as the MTAs? I just want the backend to be accessed only from certain IPs.
Do you know if the servers will have any problem with crowdsec installed at its root? It is a protection against DDOS attacks.

Jun 27, 2024A: We support every ESP there is through universal SMTP Relay.
You would add AcumbaMail as an SMTP Relay connection like this:

Everything runs in Docker containers using Docker orchestration on a private local network.
No idea on crowdsec, but you can use Cloudflare as a reverse proxy to hide your IP addresses, defend against DDOS, and act as a firewall, and you can also add plug and play HTTPS/SSL to your platform through Cloudflare.

As I have expected, your support is nothing less than amazing. I already bought one max tier. I plan to get more for the just in case situation.
One more question. Even though the servers are running inside a docker container, the front facing to the public is exposed. Don't you need some type of firewall protection?

Thanks a ton for supporting us, buying multiple Tier 3s wow what a champ.
It's hard to give a straight answer to your question about a firewall, basically our product has some ports that are internet facing like port 80, 443, and 2525 that need to be open for the platform to function properly, and port 25 for any servers running the MTA.
Using Cloudflare can help mitigate some of the general dangers of being on the internet, and it also has firewall capabilities.
Linux/Ubuntu also has built-in firewall capabilities. It's really up to each individual what they feel is necessary regarding their own security policies, and who their adversary is that they're defending against, this is one of those topics where people will quickly get riled up and start screaming at each other so I don't really want to wade that far into it 😅
