[CentOS] sendmail on Centos 7.7

Great thought to check the generated file.
It looks OK.

grep gmail sendmail.*
sendmail.cf:DSsmtp-relay.gmail.com
sendmail.cf.bak:DSsmtp-relay.gmail.com
sendmail.mc:define(`SMART_HOST', `smtp-relay.gmail.com') dnl

 host smtp-relay.gmail.com
smtp-relay.gmail.com has address 64.233.176.28
smtp-relay.gmail.com has IPv6 address 2607:f8b0:4002:c02::1c

service sendmail restart again - and same behavior going to relay
203.inbound-mx.org
