Unable to send because of 'invalid return path' about neomutt HOT 6 CLOSED

Hmm... that message has come from the server.
Your From isn't a ProtonMail address, perhaps it's complaining about that.

I don't use ProtonMail myself, but others do.
We'll see if they know

Are you using native imap setup as described here? https://neomutt.org/test-doc/bestpractice/nativimap

I think if you set password for both imap and smtp, it shouldn't prompt you for it. Not sure if there is any more secure way than a plaintext pass.

I myself use a maildir accound with mbsync handling imap, and msmtp to send emails, and both of those have password commands to potentially retrieve passwords from, say, a password manager or something.

Glad you made it work.

I tested using my proton account, and I also get an error when From address doesn't match the proton address: https://0x0.st/H0V7.png

@matthewblott Try modifying it before sending. If it helps, you can set the from email for your account with set from = "your-address"

Thanks @elshize putting the 'from' address in the config did the trick, ProtonBridge isn't the easiest to work with. I also get prompted for my password each time I open neomutt which is a bit of a pain. I've seen others with the same problem, is there any way round this?

Thanks again 🙂

@elshize I didn't know about imap_user and imap_pass, I just had my_user and my_pass set. I'm not too worried about the plain text password as it's the one for the bridge. My Macbook is also encrypted so I should be save (assumptions!). I'm all good now I think. Cheers 🙂
