Show HN: MailRender converts your emails to PDF, removes malicious scripts

Hello I'm Pierre, developper. I'd like to get early feedback about a side project I'm working on.

MailRender has a simple concept which allows to convert any email with or without attachments to PDF.

Just login to register, then send or forward an email to "pdf at mailrender.io", and you'll get an email back in your inbox with the body and attachments converted to PDFs.

There are loads of possible applications / extensions, like redirecting output email destination to another mailbox or to s3, set other MailRender mailboxes which merge or watermark pdf attachments, provide APIs for automation, etc...

The backend is a k8s cluster hosted on Hetzner. I'm basically using NATS for queing and actually 9 microservices for parallel processing. Access to the cluster have been Tailscale'd :)

There are a bunch of licensed libraries I'm using which doesn't allow me to make this project opensource. No AI were harmed during the process.
