<p dir="auto">Hi,</p>
<p dir="auto"> Actually it's a MailMate feature:</p>
<pre style="background-color:#F7F7F7; border-radius:5px 5px 5px 5px; margin-left:15px; margin-right:15px; max-width:90vw; overflow-x:auto; padding:5px" bgcolor="#F7F7F7"><code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0" bgcolor="#F7F7F7">Whenever the name part of an address header contains a @ then it’s replaced with a skull (💀). That should at least make the user aware of simple attempts to spoof an address header.

<p dir="auto">Sometimes I will receive an email that have the skull emoji (💀) in the <strong>From</strong> header. At first I thought this might be due to some autocorrect/auto-substitution that is enabled on my computer (like turning a smiley emoticon to an emoji), but that does not seem to be the case. I also looked at the raw message of the emails and didn't see anything unusual. Both these messages were downloaded from Gmail and when I look there the skull isn't present. How is this happening?</p>
<p dir="auto">Here is an example message from Citibank/Best Buy<br>
<br>
The <strong>From</strong> header is "<a href="mailto:bestbuycard@info.accountonline.com" style="color:#777">bestbuycard@info.accountonline.com</a>" <<a href="mailto:alerts@citibank.com" style="color:#777">alerts@citibank.com</a>></p>
