So, it's called fakemail but there is a real SMTP server in there. Attachments should work fine. Getting the web app to create SMTP accounts was quite tricky, I'm sure there are better ways but I ended up implementing the unix crypt() algorithm in C#.
Server is holding up fine so far (there was a rate-limiting bug which brought the site down yesterday). Logs show 37K unique IPs have accessed it since yesterday, and it seems to be using about 1% of the CPU (it's on a free VM in the Oracle Cloud).
There is a whole API sitting behind the web page, including proper authentication, but the frontend is very much a MVP.
Very few actual emails have been sent to it, so I'd love it if people could actually send stuff. There are a bunch of websites that can be used to send test mails, e.g.
