Getting multiple mails from this domain. Come back after deletion, more than once. Blocking the domain name in Outlook has had no effect.

Anything you can do from your end to get these spammers blacklisted?

The danger of spam emails- many still coming from Europe- it is a dangerous world now.

It is so easy to click onto a spam email once opened, and perhaps accidently click on reply, a link, download or attachment etc.

This can lead to fake websites, or malware downloading etc.

It can be done with an inadvertent action of the mouse/key on keyboards or on tablets pressing the screen.

I have done this myself, so by filtering spam emails away from the inbox, this reduces the chance of mistakes..

If spam emails are filtered to achieve segregation/isolation in a folder or spam folder, then there is then less chance that you will interact with the dangerous unknown spam emails. Most cyber crime, perhaps as much as 75% is due to infected emails  or phishing or spear phishing which may have Virus, Trojans, Malware, and Ransome-ware I.D.  theft  attempts, asking for bank details or passwords etc.

I also filter genuine email to other folders, so the inbox is empty most of the time, just the odd spam email gets through.

Always check the sender address, some emails may look genuine but are forged, so check the headers if in doubt.

My virgin ntlworld.com email receives so much spam  which I now monitor.. My other emails also get some spam  and the ones to watch out for are emails  you do not recognise using your email address  for invoices/purchases etc which may be unusual and need attention or fake bills/renewals.

EMAIL FILTERS- do not always work.

I have noticed that sometimes the filters glitch, and a genuine email that is filtered to a folder will bypass the filter and then get filtered to the wrong folder which may be  to the spam folder.

I have my spam settings to deliver spam to my inbox, to avoid wrong emails going to spam and set up my own filters for spam senders.

The email/newsletter  which went to a wrong folder was a genuine email I receive regularly, but always gets a spam tag, so I filter to a folder to avoid going to spam.As the filters can glitch, best not to use discard as a genuine email could be discarded.

It is easy to spot these glaring mistakes, when a filter that normally works perfectly will sometimes fail and put the email to another folder even though subsequent is not used.

It is best to keep a check on the email filtering. Fortunately the emails are not usually lost or deleted, just put in the wrong folder unexpectedly or may end up in spam, so be aware that filtering can have problems, so may be easier for some just to have all emails  go to the inbox and not do filtering if it becomes confusing and email filtering can on occasion, have unknown faults  which could result in emails not being read due to going to the wrong folder by mistake..

SOLVED

Further check found the email was sent via an email bulk sender and the sender address (NOT THE FROM)  can change by one number, in this case it was changed form @cmail20 to @cmail19, so the email filter needs to have both sender addresses.

EMAIL FILTERS- do not always work.

This can be  due to the sequence/order of the filters.

I found that one particular filter caused an issue which was filtering for keywords in the "Body" of the email so it could override other filters further down in the sequence/order

The solution was to place this filter at the end of the sequence, to avoid wrong filtering by accident, so it becomes the last filter or at least further down in the sequence/order than other folder(s) that it may be compromising

Th body filter can easily find a short keyword  by accident as it scans for the letters in the email of the body so the body condition filter may find the letters even if mixed in a block of text and thus filter to the wrong folder which is actioned in the body filter.

Most errors are down to the user setting up the filters wrongly, as in my case, but not always easy to find the error.

Spam emails sent from gmail.com, hotmail.com, outlook.com, yahoo.com, mail.com etc.-these can be fake emails.

Spammers/hackers often use and set up  these free email providers to send spam and bypass the spam filtering. (not tagged as spam)

The sender email address changes each time to avoid filters.

I have checked some of the IP addresses and they are listed on the Spamhause block lists.

These emails often have no title, no subjects , just an unknown link which will probably download malware.

They can also appear to be sent from a past contact but are fake.

The emails often repeat every few weeks, and as the IP address  which change each time and  usually  belongs to microsoft or google  mail servers, the real sender source is unknown,

These are very obviously dangerous spam emails and I move them to the spam folder. By responding the hackers may get enough information/data to attack a computer.

One of these gmail.com spam emails managed to bypass my filters today and was in my inbox, very unusual as I now filter gmail.com to spam.

The spam filters and email filters can not always be relied on to protect from spam emails, the emails may be  designed to get through any filters.

So an email may look legitimate, but and have no spam tagging, and may even appear to be from someone or a company you know, so wise to check carefully and avoid any attachment or links in the spam email.

Spam email which appears to be from a known source-

Explained here-

I've received spam from a friend – Which Computing Helpdesk

Also check the IP address source in the header, this may be a clue, if it is a UK company, but the IP address is  in Lithuania for example, then that may indicate the email is forged.

As servers are often in the USA, Europe, Ireland, UK etc, the IP address can be any country but should be hosted by the sender company, so wise to look up the IP address if in doubt.

I often receive gmail.com spam/scams- the true Ip address can be  hidden by using  an app- on a smartphone

So spammers can mask their true identity, I looked up a gmail.com spam IP address and it came up- VPN proxy detected,

Sending spam, snowshoe spamming,hijacked IP space, or associated with bulletproof hosting.

The spam email is repeated and usually each time the email address will change and also the IP is not fixed but changes each time also.

VPN is widely available and spammers can remain anonymous.

Spam/scam emails.

After doing some checks I think a lot of the spam emailsI receive  may be related to the linkedin website hacking that occured several times in 2012, 2016. 2021

see-

https://www.forbes.com/sites/leemathews/2021/06/29/details-on-700-million-linkedin-users-for-sale-on...

I did remove my VM email address from linkedin and switched to another email, but hackers are still using the stolen data to obtain email addresses and contacts to send scam emails.

They also had my linkedin password, now changed and sent it to me in scam emails.

One reason was that I had used the same password for more than one purpose, which I no longer do, to prevent a hacker getting into multiple accounts.

Hackers can use your data going back many years and are relentless in their activity, in my case probably 2016 when the scam emails started following the hacking of the linkedin data (data breach)

The best solution, which I have already done is to change email address, so no longer now use the VM email address.

Russian email scam.

An unusual  email from Russia IP address  asking me to "respond" to a yahoo email address.

The Email originated via a scam company in in the USA but registered in Moscow and receive from the Netherlands, so difficult to actually know the true origin.

The sender address did not match the reply address which is usually a scam.

The email was sent via a test therefor and had 2 sender addresses.

The email came from the Russia but originated in the Netherlands and I suspect it is connected to banking fraud and the received IP address had several different countries when I looked it up, so it may have changed recently

NEWSLETTER SCAM- is the newsletter a genuine email or not?

I do  often  receive some unknown newsletter which I have not signed up to. It is best check if you have actually subscribed to these emails in which case there would be a welcome email sent. (only if you have genuinely subscribed)

Having checked this out it could be spoofing, making you think you must have signed up for that newsletter, or registered with the company who sent the newsletter.

I checked  one today and the mail was sent via an email provider, not the usual bulk sender that the company use.

I take care not to click on any links/images in this type of email which may be a fake version but the sender  (person's name ) email may be spoofed but looks genuine.

However there are cases where the email is genuine but you did not subscribe, so someone else has used your email address to register/subscribe you for unknown reasons, or you actually have forgot you signed up, but in that case there would be a welcome email in your inbox
