Is host.satimis.com listed in your /etc/hosts file with a valid IP address?
"Frequently Asked Questions
"Question: Why do I see the following when my proftpd starts up?
getaddrinfo 'hostname' error: No address associated with hostname
warning: unable to determine IP address of 'hostname'
Answer: This error is ProFTPD's way of reporting that it was unsuccessful in resolving hostname to an IP address. Fixing this is a matter of configuring DNS for that hostname: properly set up an IP address for that DNS name in your DNS server, use a DNS name that has an IP address, or (as a quick fix/last resort) add that DNS name to your /etc/hosts file. The proper solution depends largely on the circumstances."
