ovirt in version 4.2 choose to incorporate postfix as a mandatory MTA: yum erase postfix ...

It's not about postfix being inferior or superior to other solutions. It's that it didn't ask any thing, didn't check if one was already installed. It's just installed. For example: rpm -q --provides postfix MTA config(postfix) = 2:2.10.1-6.el7 postfix = 2:2.10.1-6.el7 postfix(x86-64) = 2:2.10.1-6.el7 server(smtp) smtpd smtpdaemon rpm -q --provides sendmail MTA config(sendmail) = 8.14.7-5.el7 sendmail = 8.14.7-5.el7 sendmail(x86-64) = 8.14.7-5.el7 server(smtp) smtpdaemon There is a lot of other dependencies to declare other than postfix, MTA would have been better.

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. But email is a hard problem, not sure how complex we need to make the setup script...

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

Good question! :-) When I don't know, I usually check the git repo for previous patches' 'Bug-Url:'. In this case [1], the first patch with a Bug-Url points at a bug in product "Red Hat Enterprise Virtualization Manager", and the second one at a bug in product "ovirt-distribution", component "ovirt-host". Since your request is not specific to RHV but is for oVirt (and obviously applies also to RHV, but that's irrelevant for now), latter is the best choice.

ovirt-host have a lot of dependencies:
Indeed

Many of thee are useless depending of your setup.
Indeed, but there is obviously a trade-off here. If we can solve a bug that affects, say, 30% of the setups, by requiring a package that takes 300KB disk space, and has (hopefully) no security/administrative/etc. implications, I'd say it's worth adding.
rng-tools, for example, but my hardware don't provides any of the needed random generators. screen, tcpdump ? I'm quite surprised. glusterfs-rdma, I'm not doing glusterfs, and I don't have any hardware to do rdma
I am pretty certain that each was added with a good reason. Sometimes you can find the reason in the git commit, or in the linked bug. If you disagree about a specific item, after accepting the general reasoning above, feel free to open a bug. If you disagree with the entire reasoning, it means, practically, that you want more than one ovirt-node, perhaps many more, which will require much more work. Would you volunteer to maintain the various flavors? ovirt-node-gluster-postfix, ovirt-node-ovn-postfix, ovirt-node-gluster-ovn-postfix, ovirt-node-postfix, ovirt-node-sendmail, ... While I do not follow closely maintenance of ovirt-host, I was involved in deciding we do want it, and so far think it was a good decision. Before that, we had partial lists of requirements duplicated over ovirt-host-deploy, ovirt-hosted-engine-setup, ovirt-node (and then ovirt-release, which new ovirt-node uses), and always forgot to update some of them when adding/updating stuff. Current state, of having everything in a single (rather large, admittedly) ovirt-host meta-package is much better. -- Didi

Done:
I pushed a change for 4.3 requiring server(smtp) instead of postfix. On EL7 server(smtp) resolves by default to postfix so nothing really change except you can now install another MTA and remove postfix. On Fedora, server(smtp) resolves to exim but I added a Suggest clause pulling in postfix if nothing provides server(smtp).
