Mailer

Mailer is a multi-threaded mass-mailing script for phishing.

It accepts email templates in .eml format and supports %To_Name% template tokens (similar to Cobalt Strike).

The target list may contain email addresses in Name <name@example.com> or name@example.com<tab>Name formats.

Here's an example:

$ cat Phish.eml
MIME-Version: 1.0
Content-Type: multipart/alternative;
