Why am I receiving emails from mailer-daemon@googlemail.com?
Some months ago, I started to receive some emails from "Mail Delivery Subsystem" (mailer-daemon@googlemail.com). Despite this being an "automatic" failure email, I thought these emails were spam, so I just ignored them. But today I received many more emails, and this started to disturb me.
These emails are sent from mailer-daemon@googlemail.com (there is an icon that indicates a reply email) and says that "MYEMAIL@aol.com couldn't be found". "MYEMAIL" is the email that is receiving these messages, but with domain "aol.com" (I don't have any email from this domain).
In these emails, there is always an attached file about something attractive, like diets and wines. I think the most curious detail is that I was receiving these emails but in a "normal way". Before receiving mailer-daemon, I was receiving spam like normal, even with the same subject, and at some point this changed to mailer-daemon. Another detail is despite these emails always having an attached file, I can't see the attached file icon until I open the email. Only then, when I close the email, I can see the attached file icon. Obviously I never downloaded these files
I already changed my password, checked login's entries and everything seems to be normal. I can just block emails from mailer-daemon@googlemail.com, but I'm concerned about why this is happening
Regarding the email id - mailer-daemon@googlemail -
I've had this issue before, with another email provider. In my case, someone was able to obtain my e-mail address, but not my password. Then, my email address was used as the "reply-to" or the "sent-from" address on a spam email. It is annoying, but your email itself is probably safe. (TFA helps).
Example for clarity:
Through whatever means, I notice that a valid e-mail address is Mycroft@googlemail.com.
Now, I can authenticate to another mail server, say postoffice.com. I can then use a sendmail program that does something like this:
to: JoeBloggs@aol.com
from: Mycroft@googlemail.com
Subject: Best Diet Program Ever!!
Body: blah, blah, blah.

EOTYou will then get the mailer-daemon message, and I have not compromised your email, but I have compromised your email ADDRESS.

If you are receiving emails from mailer-daemon@googlemail.com, it usually means there was an issue delivering an email you (or someone using your email address) attempted to send. Here are the possible reasons:
1. Undeliverable Emails:
- The email you sent could not be delivered due to reasons like:
- Invalid Recipient Address: The email address you entered may be incorrect or no longer active.
- Mailbox Full: The recipient’s mailbox may be at capacity and unable to accept new messages.
- Server Issues: The recipient’s email server may be temporarily unavailable.
2. Email Spoofing:
- Your email address might be spoofed by spammers, making it appear as if the message was sent from you.
- When the fake email fails to reach its target, the bounce-back notification is sent to your address.
3. Hacked Email Account:
- If someone has access to your account, they could be sending emails without your knowledge, causing delivery failures to trigger mailer-daemon notifications.
4. Mass Mailing or Bulk Emails:
- Sending bulk emails to multiple recipients can lead to bounce-back messages if several addresses are invalid.
What to Do About It:
- Check Sent Items: Look for any emails you don’t recognize.
- Secure Your Account: Change your email password immediately and enable two-factor authentication.
- Scan for Malware: Use antivirus software to ensure your device is not compromised.
- Monitor for Spoofing: Contact your email provider if spoofing is suspected.
- Verify Email Addresses: Double-check recipient addresses before sending emails.
By taking these steps, you can identify the cause of the mailer-daemon notifications and secure your email account.

You're receiving emails from Mailer-Daemon@Googlemail.com because it's a notification system used by Gmail to inform users about email delivery issues. These emails are typically sent when there's a problem delivering an email you sent through Gmail. The Mailer-Daemon notifies you of issues such as invalid recipient addresses, blocked emails, server problems, or attachment size limits being exceeded. It's essential to check the bounce-back message included in these emails for details on why the email couldn't be delivered. If you're consistently receiving such notifications and aren't sure why, it's advisable to review your account security settings and contact Gmail support for assistance.

I got one too. Here are the headers of the bottom message (with potential unsafe data replaced).
Significant replacements:
• MEMEME@gmail.com - stands in for my address
• themthemthem - stands in for the apparent target address. (I, the fake "sender", might be the real target.)
• [10 digits], etc. - stands in for ... 10 digits (or whatever is described).
Notice the "softfail" messages all the way up.
Notice TWO "From:" headers. Is that even valid? Are the mailservers misconfigured? Do mailservers vary on whether they believe the first "From:", the second one, or both??
