Fun fact: GMail is currently bouncing with permanent errors on valid incoming mail but our 32-people "delta chat dev" chat group is not affected ... all involved (roughly 10) different e-mail servers are inter-operating fine.
@delta Do y'all have free public email servers you'd recommend? 🙂
@MadestMadness
Protonmail, tutanota have free tiers and disroot is completely free.

Follow
@MadestMadness @lps You can look through this list: https://providers.delta.chat/
Not all of these providers are free though.
@delta @lps Thank you 😊
