Stop modprobe spam

I setup GPU passthrough, it works, but ubuntu is spamming modprobe processes, it consumes lot of CPU, this is log from dmesg:

Mails sent from the command line not appearing in inbox or spam folder

I sent some test mails using the command line. In the log I can see that status = sent, but I am not getting any emails in my inbox or spam folder.

Oct 11 15:51:01 ip-10-0-1-80 postfix/local[20606]: 724AB6D5B: to=<root@localhost>, orig_to=<root>, relay=local, delay=0.01, delays=0.01/0/0/0, dsn=2.0.0, status=sent (delivered to mailbox) 

Bizarre email sent from spam email address with contact details of someone I know and a friend of their’s in it

Someone I know (call them Darren Smith) recently received a rather odd email. It was sent to their personal email address, emailaddresswithnonameinit@emailprovider.com. The “From” field had “Darren Smith” as the name in it, but the actual email address was ninerandomlettersandnumbers@differentemailprovider.com.

The text of the email is this:

NameOfDarren'sFriend, Are you free at the moment?  Regards, Darren Smith 

I have no idea what this could be, how whatever this is got the name of the person Darren knows, or how it got Darren’s original email address. Anyone have any insight as to what sort of attack this is, and what steps should be taken now?

Is this spam or scam and how does it work?

I get emails like this all the time:

Hello dear,  I’m a long time reader. I’m writing to you because I’d love to contribute a guest post on your website.  I’ve been brainstorming some topics that I think your readers would get a ton of value from:  [The Best XXXL Extra Large Electric Heating Pad on Amazon for Full Body]  I’ll make sure the piece overflows with information that can’t be found anywhere else. Looking forward to your reply.  Have a nice day,  Lekin 

It’s from an ordinary looking hotmail account, and AFAICT contains just this text. There are no links to click, so it’s not an ordinary phishing email.

If they really thought I’d like to include their content on my blog, if I had one, surely they know a spammy Amazon product name would be a turnoff.

So it feels like there’s some other agenda here, but I can’t figure out what it would be.

Spam email sign ups from HeadlessChrome?

I built a landing page with a “sign up with your email to get notified” sort of thing. The button executes some AJAX and submits to a PHP file which sends an email to me. Now, I’m getting a bunch of signups, but I’ve never advertised the link. I do see that it has been indexed by Google. These emails look semi-legitimate, but I checked my nginx access log and found they were all from HeadlessChrome (albeit from different IPs), and none of them have referers at all (I added the referer thing to the AJAX->PHP system).

So my question is: Is this spam or legitimate?

And as a follow-up, since I strongly believe this is spam, is this config in my nginx sufficient to fight it (given it’s a tiny site) for now?

server {  # (other stuff...)         if ($  http_user_agent ~ (HeadlessChrome) ) {             return 403;         } }

Postfix | Because When I send a email to Gmail, this is received as spam?

I had installed Postfix with the configuration mode: Internet SIte My file /etc/postfix/main.cf have follow it:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version   # Debian specific:  Specifying a file name will cause the first # line of that file to be used as the name.

I has edited the parameter mydestination to the SMTP server of Gmail

mydestination = smtp.gmail.com

Postfix works, I sent a email to my gmail

mail --------------@gmail.com Cc: Subject: title There are message works 

and my Gmail spam tray:

What I have to do for that the email not spam?

P.D: I followed this: https://blog.openalfa.com/como-evitar-que-los-emails-enviados-por-postfix-sean-considerados-como-spam But this doesn’t work.

I don’t want that the email is sent to other SMTP server and this send it to the destination. How to changes the mail address root@server.com to other? Thanks you
