sendmail alias expansion not working in RHEL
Issue
When sending emails from a host, aliases in /etc/aliases are ignored.
If /etc/aliases contains:
root: alerts@my.remotehost.com
Mail sent via this host for the aliased address (root in this example) actually ends up being delivered to the local account instead of the expanded alias (i.e. it goes to root instead of alerts@my.remotehost.com)
