(1001/1001), delay=00:00:15, xdelay=00:00:15, mailer=esmtp, pri=30458,
relay=gmail.com., dsn=4.0.0, stat=Deferred: Name server: gmail.com.:
host name lookup failure

smtp.gmail.com is a CNAME to gmail-smtp.l.google.com

Sendmail might not like your setting a cname there in the smarthost

Try changing smtp.gmail.com to gmail-smtp.l.google.com or do something
like [smtp.gmail.com] - note the square brackets - instead of just
smtp.gmail.com [dont attempt to resolve that hostname further and follow
things on - just connect to "smtp.gmail.com" and push email out]
