Everyone, I have had two e-mail servers running, one with Centos 6 and the other with Centos 7 using sendmail, dovecot, spamassassin, clamd, and cclamav-milter without hardly any problems after the initial setup. My expertise should be considered not much more than beginner or early intermediate. I would like to create a hypervisor with Centos 8 and run a guest Centos 8 with postfix and cyrus. I already have a guest Centos 8 on a Centos 7 hypervisor, and have had difficulty getting cyrus to work. Can anyone refer me to a tutorial on how to get postfix and cyrus to work on centos 8. Everyone seems to imply that postfix is much easier to use, but so far I have not been able to pass the low end of the learning curve. Best recommendations for a tutorial is what I would like to have. Thanks much!!!! Greg Ennis
