I'll get started on Modoboa for mail...

@stux I do not wish running your own mail server on my worst enemy... spam management is very hard to do well.

I use gmail strictly because they are so good at keeping spam out and it is next to impossible to get as good a result on a personal server.

@freemo I know, I know..

But I feel kinda desperate and don't know what to do anymore :(

For Gmail, do you use a free or paid/business account? I wonder if we can send from gmail with root domain?

@stux I dont know what your problem is or what your trying to do/solve.

I use a paid gmail for custom domains. I think the cost is 5$ a month. What do you mean by root domain? I use qoto.org for my gmail.

@freemo Well that's the issue.. It's something with DNs while that's all okay

Funny thing is.... I did had Google Business 2 days ago but switched to ProtonMail

Only for incoming mail and not SMTP though but it seemed it fcked it all up somehow

Maybe a paid Gmail is indeed the best option

@stux I'd need to know a lot more about the problem to even begin to offer debugging advice let alone a solution. Just "its something to do with DNS" isnt much to go on.

I presume you are aware of MX records and how they can dictate mail routing regardless of the A/CNAME record and all the hbroad strokes.

@stux Also be aware that changes to the DNS record can, in some cases, take up to 24 hours to propagate globally and cashed DNS servers around the world may have your old DNS information for a short period.
