I have been attempting to have my setup send email calendar notifications since I have converted my setup to use SOGo version 3 to no avail. The calendar notifications works fine which makes me think that my server email services functionality might be defective?
My mail setup runs on two Centos 7 servers. The SOGo Version version:3.2.8 front end and the sogo-ealarms-notify cron jobs runs on the Gateway server. The second server runs the postfix, cyrus, ldap & the DB services. Since the cron notification job run on the Gateway I have another postfix smtp service that relays the emails to the second server. I have tested both servers by submitting emails and that works fine via the command line. I have looked at the email log for email jobs that would have been launched by the sogo-ealarms-notify cron job and none can be found? -- users@sogo.nu https://inverse.ca/sogo/lists
