Trying to fight spam with static filters is futile. Use the built-in junk mail controls instead. https://support.mozilla.org/kb/thunderbird-and-junk-spam-messages

Hi christ1, thank you for trying but unfortunately, you've not addressed my request.

The excellent built-in junk controls do a great job but it's not an exact science and sometimes legit emails end up in the junk folder.

I and many other users need to check the junk folder on a regular basis and this is where "static filters" do save a lot of time and bother.

A filter on the Html code or even just Hyperlink code would make things even better because we often get flurries of spam/scam and while they change subject text and other spoof-stuff, more often than not each flurry has a particular (unique) link which they hope people will click on.

Filtering on unique links is better than filtering on (not unique) bits of sentence in (say) the subject.

Deleting messages with unwanted (unique) links is not only safer, but more efficient as one such filter could kill a few dozen baddies over the following week/s.

What he said is about the size of it. It is a futile process that eventually will make other things go wrong because you will potentially have thousands of conditions every email must pass to make it to the inbox.

Manual management of spam is not a good use of time and is seriously prone to error.

Try the filtaquilla addon https://addons.thunderbird.net/en-US/thunderbird/addon/filtaquilla/

But I do not think it will offer access to the raw HTML, only the displayed text. It does however offer some serious extension on the standard message filtering.

Hi Matt, sincere thanks for your input.

I agree with all points, including the risks of "over filtering" and deleting legit mail.

Indeed, it is the latter two concerns which prompted my request for hyperlink filtering.

1. Removing older (disused) filters and adding new ones is part of my existing control process which has never required more than a dozen filters. Nine at present, would be about three with hyperlink filtering. 2. Filtering on hyperlinks alone, would not delete any (of my) legit emails.

When emails appear and are visibly removed (by my filters) from "junk", and without the accuracy of hyperlink filters I must also check the "deleted" folder for an overview. An "overview" of filter-selected "junk" is much less tedious than fully assessing and deleting each and every junk email, but a chore no less. Thankfully, I do not receive much junk and often go weeks and months at a time with none whatsoever. They often seem to come in flurries.

How sweet it would be (for me) to filter on hyperlinks. Perhaps not for everyone, as you have pointed out.

Thanks again for your concern.

Best regards, ian
