It would be nice to see at least a log entry from the file. BTW
how did the hostname appear twice in the destination filename?
Either I overlooked something or you're not using exactly the

You've anchors in your filter regexps already. "^xxx", "xxx$",
".xxx." are what you need if I understand you correctly.
