Hi,
In RHEL/CentOS 7, the default mail server (MTA) is Postfix rather than Sendmail. Sendmail is certainly still available as a supported and installable alternative via yum, but unless you absolutely need Sendmail for a particular purpose, Postfix is probably the way to go. Certainly if all you want is for the server to be able to send SMTP mail, then the Red Hat default choices should be fine.
