It's caused by a sendmail misconfiguration. You must tell
mail.ermitagemontevideo.com that it should accept mail for each host and
domain that you list it as an MX for.

I do note that you have the address of linux.ermitagemontevideo.com in
rfc1918 space, but your machine mail.ermitagemontevideo.com thinks its
name is linux.ermitagemontevideo.com.
