A paying SimpleLogin subscriber got banned for using a custom domain with a specific relay. The community is roasting Proton's 'anti-abuse' logic.

We all know SimpleLogin and Proton – the poster children for privacy and security. You'd think paying for a Pro subscription would buy you some decent support and peace of mind, right? Think again.
A user recently took to Reddit to vent after getting absolutely shafted by SimpleLogin. Despite being a paying customer, their account was locked, and their data held hostage. The self-hosted community is currently having a field day with this one.
Here’s the breakdown: The OP (Original Poster) is a Pro subscriber using a custom domain. Instead of routing emails to the usual suspects like Gmail, they point their MX records to forwardemail.net – a legit encrypted IMAP storage provider.
When the OP tried to update their mailbox, support slammed the door shut. The reason? They claimed forwardemail.net is a "temporary/burner" service that causes mail loops. The OP tried to reason with them: "Look, I OWN the domain. This is my permanent inbox. Just because a provider offers aliases doesn't make my domain a burner. By that logic, you should ban Gmail too."
Instead of escalating the ticket or actually reading the explanation, the "anti-abuse" team went nuclear: ACCOUNT DISABLED.
The aftermath:
Basically, the OP is punished for using non-mainstream infrastructure. They are trying to migrate to addy.io, but they can't get their data out. It's a classic case of "guilty until proven innocent."
The Reddit thread turned into a roast session pretty quickly. Here are the highlights:
This drama is a wake-up call about vendor lock-in, even with the "good guys" of the tech world.
Proton/SimpleLogin really dropped the ball here. Protecting a platform from abuse is necessary, but treating paid power users like spammers is a sure-fire way to kill your reputation.
