I just tried with a fresh OpenSMTPD setup and it worked fine. I don’t know why 
it didn’t before. It was a few years ago that I last tried. Sorry for the noise 
- and thank you for OpenSMTPD!

It has worked for years so without more information I can't help with why it 
failed

They should work out of the box. Just sent one to myself to double check and it 
went through.

Can virtual users be used with sub-addresses, e.g user+...@virtualdomain.org ?

When I tried that (some time ago) it failed saying that the user did not exist.

I'll try to summarise it as simple as possible:

During the SMTP transaction, an e-mail address is provided for the recipient:

u...@domain.org

With a primary domain, OpenSMTPD assumes that domain.org == the local machine.
It will look for a system account matching the user and if one is found, then 
mail is delivered.
The aliases mechanism is optional, if an alias exists a transform happens, 
otherwise the username is looked up as is.

With a virtual domain, OpenSMTPD assumes that domain.org == the content of the 
virtual table.
The virtual mechanism is not optional, the recipient MUST exist in the table to 
be valid.


If you use a primary domain, when you create a new system user you can mail 
them right away.
If you use a virtual domain, you'll have to declare that user in the table.



Primary Domains vs. Virtual Domains - what's the difference?

2019-11-17 Thread Implausibility
I'm reading the man pages for makemap, and there are two types of database maps 
described, as per $subject.

What are the functional / operational differences between Primary & Virtual 
Domains?  When when I choose one over the other?  Can I get examples of when 
I'd choose a table of primary domains, and when I'd choose a table of virtual 
domains?

Which one should I choose if I want to send *and* receive mail from domains 
that are not the same as my mail server's name?  (e.g... my business has many 
websites...  example.com, example.us, example.io - and I'd like to send and 
receive mail for each of them separately...  say, to route the eMail to the 
sales rep for a specific territory)

Thanks.
