I configured sendmail in Rocky on my VirtualBox machine, just as on my CentOS 7 physical box.
Sendmail on the virtualbox machine will not send emails. Before I stay up til 2am again, is this because of virtualbox? The last entry in the maillog states service not available, but when I check sendmail service, it is running.
