That is weird.. and from all the other posts I could find on google
about this domain not good. I am not sure who 'owns' this domain but
it only shows up in malware posting and similar spaces. And here is
where:
[smooge@smoogen-laptop ~]$ host -t MX smtp-relay.gmail.com.com
smtp-relay.gmail.com.com mail is handled by 10 mx203.inbound-mx.org.
smtp-relay.gmail.com.com mail is handled by 10 mx203.inbound-mx.net.
so something is adding another .com to your domain lookup. I would
check the resolv.conf, your dns server or the configs elsewere
