Hi All,

I am 'trying' to set SMART_HOST in sendmail to point to smtp-relay.gmail.com
but when looking at the /var/log/maillog its going to mx203.inbound-mx.net.


my line from sendmail.mc
define(`SMART_HOST', `smtp-relay.gmail.com')
I did make in /etc/mail and service sendmail restart

This is the only SMART_HOST in the config file. I started with the default
CentOS 7.7 sendmail.mc and have not added anything else. just changed teh

Why is mail relay to mx203.inbound-mx.net ????

Nov 22 08:16:00 lsi001 sendmail[9286]: xAMDFxlA009286: to=
user.someone at gmail.com, ctladdr=root (0/0), delay=00:00:01,
xdelay=00:00:01, mailer=relay, pri=30197, relay=[] [],
dsn=2.0.0, stat=Sent (xAMDFxjQ009287 Message accepted for delivery)
Nov 22 08:16:00 lsi001 sendmail[9289]: STARTTLS=client, relay=
mx203.inbound-mx.net., version=TLSv1/SSLv3, verify=FAIL, cipher=AES256-SHA,
Nov 22 08:16:01 lsi001 sendmail[9289]: xAMDFxjQ009287: to=<
user.someone at gmail.com>, ctladdr=<root at machine.somewhere.com> (0/0),
delay=00:00:01, xdelay=00:00:01, mailer=relay, pri=120519, relay=
mx203.inbound-mx.net. [], dsn=2.0.0, stat=Sent (Queued!)

Thanks. How do find out why its going to the wrong place ?
