It seems that the hostname is considered as a tag name.

By checking the file runtime/syntax/messages.vim, I found it is easy to fix.

please contact the syntax script maintainer and discuss the issue with him. Thanks.

	Syntax highlighting for messages with RFC3339 timestamp (#946)
	Did maintainer reply?

It's been more than 4 years; I think the maintainer did not reply.

As suggested by the OP, this patch fixes the issue:
