+1 I bought the pro version but stopped using it because is too slow

It’s for one , but you can use a normal kvm that supports switching with the keyboard

It’s just a myth put around by some inexperienced user who has tried to set up a mail server or more likely by large companies who wants to give you ‘for free’ the service.

It was actually much more difficult to manage them many years ago when you had to invent by hand how to filter spam. Now with common standards supported by many pre-packaged solutions, everything is much simpler and accessible to the less experienced. Of course, I admit that it takes a minimum of experience to make a backup of a text file containing the mailboxes and this could definitely be the toughest challenge 🙄.

Ah sorry, I thought we were in a community that deals with self-hosting.

If you prefer to use a free provider to also have to see advertisements in addition to spam, go ahead.

If you prefer to use one for a fee because you are not able to manage it on your own, go ahead.

It’s the beauty of open protocols.

Unfortunately, in that case you will have to rely on a vm on some external provider or a smtp relay service external to your network.

I opted for a vm on the cloud, because at home I have a CGNAT network with no ip.

Turning on the server is not enough, you need to configure PTR , DKIM , DMARC and SPF. If your ip address is some blacklist it is necessary to have it removed. Once this is done, it is rare for emails to go to Spam other than for content control.

Thank you, I will keep an eye on them in case of any problems with docker-mailserver 👍

Until I discovered docker-mailserver 😉
