Could be an inside job, too. A few weeks after a merger which gave me a brand new email address I never used anywhere, I started receiving spam on the unused address. I figure that one of the thousands of third party contractors scraped the whole address book and sold it for a few dollars.

The solution of last resort, IMO. You're seriously inconveniencing all your contacts more than anything else.

And it's not much of a long-term solution either - the reality is, you don't have to give out a new email address to anyone for the spammers to start sending junk to it. It'll be discovered sooner or later, and then they all start sharing the address with their buddies.

I've registered accounts with variations of my name on a few of the more popular free email systems, and I can guarantee some of these have never been shared with anyone. That includes systems that have been put together by people who (you'd think) have a pretty good grip by now on how to handle spam (Gmail and Outlook among others). Yet spam still makes it in. That means there'd be plenty more coming in on systems that aren't as good at identifying spam.

Yep, and that's the point. There really isn't any way to stop getting spam, either short-term or long-term.

You can create a new address. You'll stop getting spam, but only for the short-term.

Speaking as someone who has run Exchange since 1994, i can tell you it is a pretty complex subject. It's a whole science. The technology is always changing, the criminals are finding new ways to try and exploit people. It's a war.

It's a war I mean to win.

But you have to keep on top of your edge firewalls, examine logs daily. DKIM and SPF are critical. Careful configuration of DNS based blacklists are critical.

99.99% of spam is dropped by simply blocking non-conforming inbound messages. I then have my firewall block their subnets for a year to cut the noise traffic.

Right this minute I have over 1/2 million subnets blocked on an edge firewall... All of that is totally automated but I have to keep on top of it to make sure nothing gets through.

On our entire infrastructure, I can remember getting 1 spam email in the last 2 months. (the firewall drops about 1 a second).

Hi Sander,

That is really odd. I have had a Gmail account from more or less when they became available ( 15 odd years ago or so ) and I have to say Gmail has always been quite good at blocking spam etc... Something slips through every now and again bit it is very rare. I wonder why yours might be doing so much worse.

Every now and again I have look at the spam folder just to see how many Nigerian princes are willing to share hidden funds with me, after paying a certain amount of money to get access to them of course. Laugh | :laugh:

Sander Rossel12-Jun-20 5:18

12-Jun-20 5:18

Yeah, me too.
GMail is pretty good, but since a while, about four a day slip through.
It happens more often, but never more than a few days so this has been going on far longer than usual.
There's still a good chance it will just stop at some time though.

Best,
Sander

The other problem is, GMail blocks emails that aren't spam. I used to get 40-50 spam emails a day although it's dropped to 20-30 in CoViD-19. (Why?)

Maybe 4 or 5 a week would be emails which should have got through.

So I check my GMail spam folder every day.

Sander Rossel14-Jun-20 22:28

14-Jun-20 22:28

I read ALL my mail, so if I get a spam message my spam folder will go to the top and show (x) unread emails.
For some reason, almost all my Microsoft/Azure/DevOps newsletters are spam so I whitelisted the Microsoft domain.
Other than that it rarely happens though.
Four to five a week sounds like a lot, are they from the same person/company?
If so, consider whitelisting them.

Best,
Sander

All I can say is don't bother setting up rules if you're using Windows 10's built-in email client. I don't know how Microsoft can claim it works at all.

I have the same experience. Windows 10 Outlook NEVER properly handles spam. It allows dumb stuff through and filters out emails from people's email addresses that I've authorized/white listed. Fairly worthless spam filtering!

Basildane12-Jun-20 2:53

12-Jun-20 2:53

I would be curious what the domain was for your spam you are talking about.
I've gotten to the point where I can recognize a "NameCheap.com" spam without even doing a Whois on it.

Did it come from a .info, .xyz, .pw domain for example?

You need to 100% block ALL of those - permanently. They are 100% spam.

Sander Rossel12-Jun-20 3:24

12-Jun-20 3:24

Haven't checked, I just had one from .us.
I don't doubt that it is spam, even without looking at the domain.
It gets in my spam folder, but I really just don't want it at all.

Sander

Oh oh oh oh!!!!

Please do a whois lookup on that .us domain. Or just give me the full domain name I will do it.

PLEASE

I want to hear.

Sander Rossel12-Jun-20 3:48

12-Jun-20 3:48

V683V6PKG.us, no data / failed to get data.

This is the first time I looked at the domain name.
Tomorrow I'll probably get it again, but with another generated code.

Thanks for posting that.
I'll bet if you look deeper at the headers you will find the TLD that points to Namecheap.com as the registrar.

I've been fighting this war with them for 10 years now.

I will bet my left nut it's Namecheap.

Sander Rossel12-Jun-20 3:56

12-Jun-20 3:56

I already deleted the email.
I'll keep an eye on it when I get new ones.

Sander,

Outlook client lets you view the email source and the Internet headers so you can see where the email actually came from (see sample below). I do not use Gmail I do not know if it has the same capability.

You are absolutely wrong - fortunately (for both of us?) I never have or will need to send you email.

I have used, for over a decade, a .info domain as one of my personal domains.

From this and another of your emails in the thread, I can assure you that you've already lost the war as they keep you busy trying to keep on top of them. How much are you paid for your time?

Or, how much broad-spectrum blocking, the good with the bad, are you willing to accept? Again, they win! You will not receive email that wasn't spam because you blocked it.

Or even more maintenance to unblock those blocked by your bulk practices.

I've found that the biggest place that SPAM comes from is a DOMAIN registration.

Do you have a web domain registered somewhere? Check and see if the admin email address is the same as the one you are getting the spam at.
