CentOS 8 Postfix & Cyrus

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

    Attention Greg, so-called tutorials do not tell you what you need to know about Postfix. Consult the original Postfix documentation.

    Configure Postfix to us relay_transport for the hosted mail domains feeding Cyrus-IMAPd on LMTP. And make sure you define proper relay_recipient_maps (or virtual_alias_maps).

    relay_domains = example.org relay_transport = lmtp:inet:[1.2.3.4]:24
