As you can see, sendmail does not appear ... How can I fix it?
This could be ugly. Installation from source, even correctly done,
interferes with OS features like this "alternatives" thing. It is
well worth your while to spend some time learning how properly to
manage your OS before undertaking mail admin.
With Redhat-based systems, I suggest using Simon Mudd's SRPMs for a
recent Postfix release.
As to how to repair the damage, that would be a matter for your
CentOS documentation and forums. Good luck.
Using source is fine and necessary at times when you can't wait for
certain vendors to fix things on their time frame. We run source for
several things. You just need to manage it accordingly.
In fact, I have found more than one borked rpm with wrong install
dependencies, incorrect configurations that break things or overwrite
prod configurations or incorrect remove dependencies.
Does postfix compile without sendmail by default?
You could recompile if you feel comfortable. Fairly I would do just that
but I feel comfortable with this.
