Well... some links can. For example, if it is an Amazon link, that link is individualized to you, and tracks you. They will know that you clicked on it and you had a look at that amazing USB powered nail polisher. And then, you will be pestered with a zillion more mails about shoe polishers, glass polishers, keyboard polishers, etc etc :-D

For Windows, the verb "open" may have a different meaning.

The vast majority of Windows users run in administrative mode all the time. If they "open" an email with an executable it can run and install whatever it wants to without their knowledge. Linux users do not run with administrative user privileges all the time [ as a rule ]. Executables cannot just run. They have to be run intentionally. Windows CAN be set up that way and all the Windows machines I set  up are, User and Administrator.

In Linux, no matter if done as admin or as user, opening an email with an executable doesn't run it. You can not even double click on it to run it. However, a document with a script inside can be loaded and opened. A PDF can contain javascript, but we don't have any PDF reader that supports javascript. Acroread from adobe did. I don't know if some other proprietary reader does. Foxit? A Libre Office document can contain scripts, but by default running scripts is disabled. -- Cheers / Saludos, Carlos E. R.

heh, no, it is firefox in the back, after he did click on the bad link. These guys invented a login which is generic, not really from opensuse.org, that includes a Norton security logo. But opensuse.org "mail" login does not even exist, it is not a "mail server", just a redirector. And opensuse-project@opensuse.org is a mail list, not a user. These bozos didn't investigate.

I understand that this is.

I have already confirmed that filtering actoin is not the same as opening an email, in the way I will describe later.

When choosing an email reader for the very excellent software recoll, I tested with Thunderbird, sylpheed and kmail, and chose kmail as a result.

Of the three, I found Kmail to be the most secure. I was very surprised that it requires approval to display internal links. Needless to say. This was not the reason for choosing Kmail, but because it look and feel was the best.

I tried kmail in the long past, and did not like it, was "incomplete" for my liking.

I fully agree with you.

CER> For Windows, the verb "open" may have a different meaning.

I can't understand what you mean.

"open" in Windows also means "run", "execute".

The "delete it immediately" means don't even click on the email. On a smartphone, it means don't even tap (I didn't use a mobile phone and I never use a smartphone, so I may have misunderstood.).

Yes. But I can not delete an email without clicking on it, then hit delete. Anyway, I never delete email, not even confirmed virii :-)

Ah, I see. Thanks.

BTW. The reason I say don't open suspicious emails, even on Linux, is because I fear the unfathomable technological advances of spammers.

Well...

Even now, it's often said that there is still a lot of spam originated from linux machines, though it is a low percentage of the total computers. Of course, this is a phenomenon originating from the port 25 issue.

Hum.

2. on email filtering

As many of you probably know, there is the mail management softwares. Using this software, it is possible to check (multiple) sent e-mails to see;

1. when the email was delivered to the recipient 2. when did the recipient open the email (not necessarily once)?

Yes, but this depends on the client of the destination collaborating. It needs that the receiving client sends a "receipt" confirming delivery or reading. Thunderbird read receipts are configurable. I don't know what action is the default, but mine is set to always ask. AFAIK it does not respond to receive receipt request, which are processed my SMTP servers, and not all (usually only the sender server). The other method of confirmation is that the receiving client displays remote content of the html side of the post, like a photo (or a zero size photo). Thunderbird asks before doing this by default.

This is a software for advertisers. When I did the 'filtering test' using this software, it did not recognise the email as 'opened' and the email remained unread for a long time. So, the filtering is not equal to opening.

Ok.

Anyway, it seems to me that spammers are using this software.

As I've been sending spams to /dev/null with the filter, I feel that spam from Russia stops sending spam in a few months, and spam from China in about two years,. Spam, which spiked as soon as the whole country went into home mode during the new corona pneumonia scare, has also dropped off sharply here. This is how it is in my case, but there is no change in the situation where spam is raging among the public and public authorities are actively ventilating caution, which is the current situation in Japan.

I wish Japanese spammers could also use this software for advertisers.

I get very little spam. Depending on the mail provider, some are very effective at filtering spam or virii, like gmail. Others have too many positives, so I disable it (gmx). -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)
