Description:

The file apps/meteor/app/lib/server/lib/defaultBlockedDomainsList.ts contains corrupted entries in the emailDomainDefaultBlackList array. Two domain names were accidentally joined into one string without a separator, creating entries that will never match any real email domain and silently fail to block disposable email registrations.

Steps to reproduce:

Run this from the apps/meteor directory:

node /tmp/v.js

Expected behavior:

Every entry should be a valid standalone domain name that correctly blocks

registration from disposable email services.

Actual behavior:

Fused entries — two domains merged into one string, will never match anything:

Truncated entry — missing TLD, will never match anything:

Duplicate entries — exact same string appears twice:

Impact:

Because the fused entries are syntactically valid strings, no TypeScript or lint error is thrown. The bug is completely silent. A user can bypass email blocking

by registering with [test@mailmetrash.comilzilla.org](mailto:test@mailmetrash.comilzilla.org) and Rocket.Chat will accept it even though [mailmetrash.com](http://mailmetrash.com/) is explicitly in the blocklist.

Additional context:

The fix is to delete the 3 remaining fused lines (both halves already exist
correctly elsewhere in the list), fix viewcastmediae → [viewcastmedia.eu](http://viewcastmedia.eu/),
and remove one of each duplicate line.
