We compared 20 international popular email providers considering performance, practicability and transparency as main criteria to find out which providers work well with Delta Chat. We published a table with the measurement results in our blog: Which e-mail providers work well with Delta Chat? Quite some :) - Delta Chat
In the table you will see both qualitative and quantitative evaluations. We measured things like message sending speed, attachment size, steps for the set up with Delta Chat, IMAP features and more. Please let us know what you think about it!
Welcome!
I have no experience with DreamHost. But I would generally recommend using a chatmail instance. These are free and better suited for chatting than regular email providers. Plus, they’re quicker to set up. You only need to enter a username.
I’ve been experimenting and dreamhost works, but, yes, dedicated relays are much snappier.
i looked at hosting a relay behind an nginx here at home, but gave up when I realised the complexity of the setup; and dreamhost’s DNS config interface refused to allow the recommended CAA entry.
