Well the link kind of doesn't help, because there is no amavisd.conf file anywhere to be found.

So you just searched text "amavisd.conf" on that page and closed it?

Again:

- Some linux distros use "amavisd" as the command, but some uses "amavisd-new".

Really?!  First I tried iRedMail on raspberry pi 5, but it had limitations.  Then I changed to Debian 12, on i5, and followed iRedMail-1.7.1 instructions from iRedMail website.  amavis seems to have most everything except the command itself.  How can I install it or add it without going through reinstallation of iRedMail.
???

Yep, fresh install on a Ubuntu 24.04 Staging Environment,

You can see the fresh install here on stag04 has Amavis & it's configs present, latest 1.7.1 as of this post.

I do not have amavisd-new.  it says command not found

Are you sure you are using iRedMail? I would suggest starting from scratch and install https://www.iredmail.org/download.html

On all installations of iRedMail amavis-new has been installed.

Regards

Sorry the only location that I found for the amavisd.conf file was mentioned in my original post which was not answered in its entirety. 

Question: amavisd.conf is in iRedmail-1.7.1/samples.  Do I edit the amavisd.conf in samples or is it to be moved to another directory?

No leave the sample.conf alone. When you do sudo amavisd-new showkeys do you get a output ?

You only need to edit 50-user

 sudo nano /etc/amavis/conf.d/50-user
 
 Find the following line,
 
 dkim_key('domain0.com', 'dkim', '/var/lib/dkim/domain0.com.pem');
 
 Add another line with,
 
 dkim_key('domain1.com', 'dkim', '/var/lib/dkim/domain1.com.pem');
 
 look for the line dkim_signature_options_bysender_maps then add,
  
 "domain2.com" => { d => "domain2.com", a => 'rsa-sha256', ttl => 10*24*3600 },

 Once done run the following,
 
 sudo amavisd-new genrsa /var/lib/dkim/domain1.com.pem 2048

 Change Permissions,
 
 sudo chown amavis:amavis /var/lib/dkim/ -R

 Restart Amavis,
 
 sudo systemctl restart amavis

 Then run the following,
  
 sudo amavisd-new showkeys

Once you got the new keys, add a TXT Record to your Name Servers.

Question: amavisd.conf is in iRedmail-1.7.1/samples.  Do I edit the amavisd.conf in samples or is it to be moved to another directory?

I'm really at a loss on this issue.

Actually, can I use the current dkim key that iRedMail generated for my domain and use it for all other domains?  If so what would I need to do?

Thanks
