I get all two days a (porn-)SPAM, which constant is only, that there is a link in the mail content, starting with this string characters:
<!-- I guess, just because of that signs the Power Mail Filter (set on: Content - contains the exact phrase: "<!--") can not identify this "phrase". Any idea how to filter-it? (All other content before and after the link, which starts with that string-sign is always a different accumulation of meaningless words - nothing for a filter command.)
