I've successfully set up a mail server using iRedMail on Ubuntu 20.04. While testing my server, https://www.mail-tester.com/ reported only one problem - Your message is not signed with DKIM.
The fact is I've already set the DKIM entry in my DNS settings, but still I get the same error, thus my emails end up in the spam folder.
What am I doing wrong?

I recently changed the nameservers on Godaddy to a private namesevers pointing to an ip. The website seems to be working fine with Google DNS but its not accessible on wifi in my country
If you have just recently changed or updated the DNS records on your Godaddy management page, this might not be accessible.
Normally, this will take up to a maximum of 72 hours to propagate the Internet.

I'm trying to setup incoming email for my Amazon EC2 linux box. Namecheap Private Email records for domains with third-party DNS
My domain's DNS is managed through NameCheap. They have a private email hosting service.
https://www.namecheap.com/hosting/email.aspx
Will this enable me to have a webmail interface where I can send / receive emails from my domain?
I checked your domain and it does not have any MX Records setup. See screenshot below. That is the reason you are not receiving the emails.

I have been changing my mailing addresses from "example.com" to sub domains - say "mail.example.com" to configure no-reply addresses there. I use "sendmail -f noreply#mail.example.com" to send emails making sur ethe Return-Path is correct. My mail delivery chain looks as follows:
SENDING SERVER --> relay_server --> gateway out
For unknown to me reason when my email reaches the gateway that sends out, I see that the "from" address is already altered in the postfix log file to "noreply#example.com". This is also what I see in the detailed message log when it reaches its destination.
I have seen similar topics over here, but I made a step ahead and checked that I use the "-f" sendmail switch.
Any clues?
After the entire weekend of troubleshooting this I eventually found the reason:
http://www.postfix.org/postconf.5.html#masquerade_domains
plus restart of all postfix-related deamons (postfix, dkim and all that) helped.

How would I go about adding an account to Postfix and secure it with a password?
I've already setup everything else, and root works.
The simple way to add a user is to simply add a new account on the system. Postfix will handle the rest.
If you don't want to create a system account for the user, you should have a virtual domain set up that is not configured as a mydestination domain. For more on this, be sure to read the Postfix guide on virtual domain hosting.

Here is the situation, we have a linux web server that runs Plesk and I need a way to intercept emails sent to and from the server. Plesk uses qmail to send and receive emails.
We have sorted the receiving emails problem by adding a mailgroup to each email address that includes an "archive#" address. Then we use a PHP script to read the "archive#" mailbox and puts the emails into a MySQL database.
My problem at the moment is how to capture the messages sent from the server. Has anyone had any experience in doing this?
Thanks
Peter
this can be done via QUEUE_EXTRA (http://www.google.com/search?q=queue_extra), for which you need to recompile qmail. some hints on doing this on plesk here (http://translate.google.com/translate?hl=en&sl=pt&u=http://www.maglione.com.br/artigos/artigostecnicos/pleskqextrahowto).
