At the time of this writing, there are 432 pages in this forum. I can find no way to search topics, so ... I apologize if my questions has been asked and answered. Any help would be greatly appreciated!
All IPs and FQDNs are illustrative.
I have 2 VPS setups:
NextCloud, testing, etc at 200.1.2.3 as example.net
iRedMail at 210.3.4.5 as mail.example.net
I want all email - user@example.net - to be processed by the 2nd VPS (210.3.4.5 a.k.a. mail.example.net)
For my domain (example.net), the DNS configuration is as follows:
A @ 200.1.2.3
A mail 210.3.4.5
CNAME cloud example.net
CNAME www example.net
CNAME blog ghs.google.com
MX @ mail.example.net
I have chosen to use RoundCube as my webmail client.
I have two users: postmaster@example.net and liam@example.net
Using RoundCube, I can send mail successfully (although many systems file it as spam).
Sending from Yahoo!, GMail, etc. to liam@example.net results in an eventual send failure.
I then tried two tests from the command line from a 3rd remote, shared server. The first (to liam@example.net) should have succeeded and the second (to liam@mail.example.net) should have failed. They both failed - i.e. no mail was ever received - but in different ways.
The one that should have succeeded: mailx -v -s 'Testing from cmdln' liam@example.net
