Tutorial for secure emailing with personal domain,Cloudflare, virtualmin and postfix

Indeed. +1 for telnet.

I just trusted the netstats which told me that everything is OK which is certainly the case on the server.

since I didn’t have Telnet on hand I tested a website which told me OK

I have to confess, I installed the telnet-client on your server for diagnostic purposes.

I will make them an unblocking request.

Curious to know how you got on with this…

[DownPW]

sorry for the late response my friends. They unblocked port 25 very quickly and I can send emails;

Just that the domains in caramail.com refused my sending of email for obscure reasons and protonmail, I receive them but in spam with an error message

I will share all its errors with you to see and I would like to deepen that the DMARC, and DKIM puts the private/public key which I do not really understand (see my request above)

@DownPW emails are going to junk because of missing DNS records as I mentioned previously. You won’t need to use the public and private keys unless you need extended and/or advanced functions.

[DownPW]

I have the DNS pointers present

@DownPW not all are there. The SPF record is missing. That’s enough to place email you sent into junk at the recipient end.

Spf is on the screenshot

@DownPW sorry, yes, it is. Completely missed that.

@DownPW Can you PM me your domain name so I can run a few tests?

[DownPW]

Yep no problem

[phenomlab]

@DownPW thanks. See PM. You can validate your domain in terms of its email suitability by using the checker below
