I have been receiving a lot of phishing attempt e-mails lately that have a "from" address like this: [email protected] <https://www.exquisiteimages.com:2096/cpsess1855114148/3rdparty/squirrelmail/src/compose.php?send_to=valid.user%40mydomain.comaccounting>@someotherdomain.hn
This appears to be an attempt to fool anyone who isn't paying close attention into clicking one of the links in the message since it appears to come from a valid user inside my domain. I am wondering if there is anyway that I can stop messages with "from" addresses like this.
