This was added in 4.0, AFAIU: https://bugzilla.redhat.com/show_bug.cgi?id=1301966 IMHO the bug is somewhat incorrect. HA sends its email using smtplib, which IIUC does not require a local /usr/sbin/sendmail . Indeed, the default is to send through 'localhost:25', and for this to work you need some MTA listening there. But admins might find it perfectly reasonable to not have any sendmail locally, although this is the unix tradition, and configure everything to send through a remote MTA. hosted-engine --deploy already asks about this, so should be easy to do there. Other common stuff, such as crond, also allow doing this. So ideally, if the admin accepts the default 'localhost:25', the script should try to connect there (perhaps also if user provides custom values?), and if it fails, or if the other side does not look like an MTA (e.g. does not accept a HELO or EHLO, not sure what's the best way), prompt, and if 'localhost', suggest to install some MTA.

I agree, and suggest to open an RFE on ovirt-host (and elsewhere? didn't check) to change the Requires:. Seems like the thing we want to require is 'server(smtp)': https://fedoraproject.org/wiki/Features/ServerProvides Best regards, -- Didi _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/4LUVNYZGJME4JEOJM4HKVL4OTP4PL5D2/
