Weāve got 3 realistic options.
- Best fix: repair Himalaya sent-folder config
⢠Right now SMTP send works, but Himalaya fails when it tries to save a copy to the sent mailbox.
⢠If we find the exact iCloud folder mapping Himalaya expects, auto-reply becomes clean and normal.
⢠This is the best long-term setup.
- Safe workaround: custom reply sender
⢠Keep using Himalaya for reading.
⢠Send replies with a small custom SMTP script instead of Himalayaās broken send path.
⢠Then optionally save a local log of sent replies instead of relying on iCloud Sent.
⢠This is probably the fastest reliable fix.
- Ultra-safe mode: draft only
⢠I generate the reply draft, but do not send automatically.
⢠Lowest risk, but less autonomous.
My recommendation:
⢠Use option 2 now, then I can separately debug option 1 in the background.
⢠That gives you working auto-reply soon, without waiting on Himalaya weirdness.
If you want, I can build the custom reply path now and test it on a harmless email.
