2 GBmemory is required for a low traffic production mail server, but
4 GBis strongly recommended to prevent ClamAV eating too much memory for big virus signature database.

OpenBSD release number):
Make sure 3 UID/GID are not used by other user/group: 2000, 2001, 2002.
No matter your server is a testing machine or production server, it's strongly recommended to set a fully qualified domain name (FQDN) hostname.
hostname to view the current hostname:
$ hostname mx.example.com
On OpenBSD, hostname is set in two files:
/etc/hosts: static table lookup for hostnames. Warning: Please list the FQDN hostname as first item.
# Part of file: /etc/hosts 127.0.0.1 mx.example.com mx localhost localhost.localdomain
Verify the FQDN hostname. If it wasn't changed after updating above two files, please reboot server to make it work.
$ hostname mx.example.com
iRedMail will install all required binary packages with command
from mirror site defined in file
installurl(5)), If no mirror defined,
iRedMail will use the fastly CDN
for package installation.
