EMAIL FILTERING HICKUP'S- emails going to wrong folders.
I have recently had some emails going to the the wrong folders, and having inspected the filter keywords it should not be happening.
So the filters, as others have mentioned in posts, are not always reliable, especially with "new" emails/new senders/spams.
This results in spam getting through and not being blocked, I had a new newsletter spam to my whitelist today, many of the spams may be spoof as they apear to be from the uk/local but are sent from servers in the usa and I had not subscribed to them.
I have now changed some of my filters to be more acurate and try to eliminate the mistakes, which means I put the full email address rather than just part of it for whitelisting, and for other filters still use some keywords, but the shorter keywords often end up in wrong folders, for example a keyword "test" will often go to the wrong folder, filters seeming to pick up the 4 letters whatever sequence they are in using random letters in the condition from or subject.
Some miss-filing's are totally un-explained, and I think the system just gets confused at times so the filters can glitch at times or problems with the settings server.
My spam has reduced, not sure why but over time spam emails can increase or even stop for a while.
Some spam emails are probably stopped by the server poviders blocking them, which works until the spammers switch to other servers, in some cases spammers may have their own servers or pay fees to providers to send spam or use bulk emailers.
I get newsletters that I have not signed up to and have had approx 50 to date, some are not repeating, other do repeat but only a handful.
It is however unusual to get a newsletter out of the blue, which normally requires subscription with name, address, email and in some cases phone number, so perhaps they are using lists to spam people or others are signing up for me?
In some cases the newsletters may be spoofed or fake versions of a real newsletter.
Some look genuine but as I have not signed up to the newletter I do not click on anything in the email.
I sometimes do sign up to the genuine newletter and compare that to the unsolicited version received.
I usually do know which newsletters I have signed up to and keep a record of that and which email was used.
Somtimes email goes to the wrong folder, so I am now trying condition "is exactly" and putting "from" - the full email address for whitelisting
Forwarding does not always work, the odd one fails to forward.
The setting in one filter "action" file -changed by itself resulting in emails going to a wrong folder (was set to spam but went blanc)
At present the action part of the filters setting is locked by a red "no entry sign" so although I did update it then locked me out.
I keep trying to improve the filters but think in some cases the filtering can fail or setting change by themselves for some reason.
I have now placed extra keywords to try to eliminate the problems and because most of my spam is from gmail I am filtering all @gmail.com to spam, must be worth a try, as I have no contacts using gmail.
I am now filtering known contacts to the inbox (easier that way) and all other emails to spam using from @ but also including @gmail.com and may add others if needed.
I am also using blacklisting, which puts many emails into the spam folder.
So filtering can be random and can be a challenge to keep the inbox totally clear of spam, one always gets through.
.... I've hardly had any rubbish even into my spam folder over the last few months, let alone in my inbox. The servers sending this crud out seem to be getting effectively blocked. I'd highly recommend giving it a go.
Rather than simply forwarding the spam-crud directly (you could try though) as this might get blocked by Virgin's filters 🤔🤨 !!! ... I tend to "Save-as" a *.eml file and forward the saved file(s) (as a batch) to the email I gave above. No need to subscribe and it's automated apparently - sending you a brief email of confirmation as soon as they receive your files (so no need to write anything in the email you send).
It took a few sendings of a number of crud, but whoever was sending it out soon got stomped on by the looks of it 😁
The filters I'd set up and used for some time (I've not needed to use or update them since using the phishing service) if you wish to try them are here - take a look at the filters to only give you ideas on what to put in yourself, as they're likely outdated by now. ....
