Hello,

I am using OpenSMTPD with the following;
Maildir
Dovecot/LMTP
Spamd
Dkimproxy
Dmarc (Domain)
SPF
Let’s Encrypt Certificates
Simple script for Spamd to obtain RBL lists
Filters for fcrDNS
Mutt Client
Virtual Users and Local user
Backup Mail server using Dovecot replication (Located in another country)
Dovecot Sieve for placing mail into particular folders
Rain loop WebMail client (running on another OpenBSD box)
Basic Monitoring using Monit

I am not using any backend Database.

The mail system I have configured is for me and a single domain at present. I 
don’t have any intention of scaling it out as I wanted to get off Office 365 as 
my primary aim. I like the control and being able to manage it, learnt a lot 
along the way.

Not sure if I gave you any answers but the information is out there and it 
takes time to get it right and obviously to meet your needs. The information in 
man is also very good as you know.

All my OpenBSD boxes are running at Vultr in two locations.

Good luck with your project, Happy to provide more information but better if we 
do that offline.

Nino
