Certainly. But that's not the majority. There is a demand/request for removing postfix from the default install.
That disappeared long ago. Precisely because of daemons such as crond, mdadmd, smartd needing a place to report their results. Makes me wonder - how do systemd timers handle the output? Just wondering out loud, I hadn't thought about that one before.
I don't know, either.
Even if no cron job and no other daemon will use sendmail to drop mails into the queue, postfix is still started, it's the default.
True, but ignored. There are people that don't know it is there and are surprised when they find out. Then some want to remove it.
I think you missed the point - postfix is started and runs, with no problems, in the default config. If people don't know about it, that's their problem :-)
Yeah, I know it runs fine by default.
Also, I still don't see how that 127.0.0.2 entry will make postfix fail. postfix, by default, only listens on "localhost".
Well, it does.
I submit - in the default config it does not. When you then change the config, it's entirely up to you.
Maybe if it "knows" the machine name is gaston.local.net then it tries to locate the interface; hosts says it is 127.0.0.2, and then fails to bind to that address, it has no interface. Something like that.
There is no black magic here, postfix does exactly as it is told. In the case of 'gaston', postfix never touches eth0, it only listens on loopback. Of course, if the config is changed to include listening on 'gaston.local.net' = 127.0.0.2, then postfix will fail.
But all my LAN machines with openSUSE (except some test partitions) have a postfix that listens on the eth0 or wifi port and accept/send mails to other machines in the LAN. I have to change the default config for that - and typically, I use the YaST mail module for this change. Now that in 15.1 the 127.0.0.2 line is not created, I don't expect that problem. There might be problems with some other applications (I don't remember which) that required that entry. -- Cheers / Saludos, Carlos E. R.
