Help; I'm drowning in spam!

I have used Thunderbird for years.  The Junk Mail adaptive utility has worked very, very well for me.  But starting about a month ago it has just died.  I get about 500 spam emails a day into my various email accounts.  Having used it for a long time, yes, I have adaptive junk mail filter selected, and move to my Junk folder selected.  But now only about 20% get flagged, and half those that TBird flags as spam actually move to the Junk folder.  I have set my server to do filtering; very little improvement.  It is also adaptive, in that if something gets through I can drag it to the Spam folder and the filter will learn from it (this is an IMAP system, so the server can see I have moved it into the Spam folder).  I have tried pretty much every spam filter service available that does not require I have all my email first go through their server, but maybe I need to throw in the towel on that.  Most recently I installed the Avast!! system, which claims to protect against everything including spam, but saw no improvement at all.  I could not see that it was doing any filtering at all, so I called Tech Support and it was clear that their technician's job was not to fix my issue but instead sell me a $180/year maintenance package (with the usual "clean up your registry") , and that then they would take an hour whilst logged into my system to "fix" it for me.

My resistance to server-side filtering at the domain level is that others in my company and family would be effected, but if it gets down to it I guess I would do that.  But I'm getting about 500 / day.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you're not willing to do server side filtering then you're stuck with the usual Avast, Kaspersky, Mcaffee endpoints systems to filter for spam at the desktop level.

If you can, turn on greylisting at the server side and it will bring down the spam by at least half from my experiences.

Another option would be to route your mail via an email filtering service and then have it forward to your own mail server.  We deploy this in many environments and find it the most effective way of dealing with spam.

I can recommend McAfee MXLogic for this service.  Spambrella are a good reseller of the product which I also recommend.

Thanks fellas; I'll look at both.  I just got offered to install the latest beta of TBird, so think I'll give it a chance.  It used to be really good, now it is really crap.  I even installed a down rev from a year ago and it made no difference, which I don't know what to make off.  Since I'm not a pro reselling to a client I would not go for a $40/month deal, but would consider a few bucks a month; anything is better than this.
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

Newer TBird did not improve at all.  Looked at the suggestions, and way too expensive.  I am not reselling to a client, it is for my own email.  With my various business interests, I have email through three different domains.  Just got a quote from SpamHero for $21/month; really want to not go there if I don't have to.
Hi Mike,

Sorry to break it to you but I've done many research on cost effective antispam solution and most of the free ones were just not good enough and the desktop version is normally not a solution I would push to my clients.  It's always best practice to filter spam at the server level or before it get to your email server.

However, you can try each one of these if you want and you may find something you like Top 12 Free Spam Filters for Windows

The MXLogix solution costs about £2.70 a user.

It's not that much money if you work out the abound of time you're probably losing by deleting and checking the spam on a daily basis.

In addition MXLogix scans for viruses and acts as a spoiling service in the even your server is ever down.

I'll have to look again then; looked more like $40 when I checked it out.  I don't require free, just trying to keep it down.
