Introducing MailCrab, the crustacean of the email testing world that's ready to snap up all your development emails in its claws! This nifty accept-all SMTP server isn't just another pretty shell; it comes with a web interface that lets you spy on your emails like a secret agent. Peek at formatted emails, snatch attachments, scrutinize headers, or dive into the raw email abyss. It's a dockerized delight that scuttles across both amd64 and arm64 platforms with ease. Crafted in the robust and speedy Rust language, MailCrab's backend is like a treasure chest that hoards your emails in memory's locker, while the frontend is your trusty periscope to the sea of messages. It's smart enough to fetch all your email metadata with a single call and then keeps an eye out for new messages with its websocket tentacles. Want to read a message? Just poke the endpoint, and voilà! Plus, with a few secret commands, you can mark messages as read, make them walk the plank one by one, or unleash a kraken to wipe them all out. Host it on RepoCloud, where the costs are as tiny as plankton compared to other cloud hosts, and you'll be sailing the high seas of email testing with a grin as wide as a whale's!
