We are aware of roskomnadzor just having ramped up their blocking efforts in #russia against #deltachat 's default onboarding chatmail relay. Signal, Whatsapp are degraded/blocked for a longer time already.

1) Delta Chat has first class shadow-socks proxy support (try ss:// links you can find ... Delta has management-proxy UX)

2) many other chatmail relays work fine and inter-chatmail/email server traffic continues unimpeded

3) if you can help with analyzing please drop into our DMs.
