Prerequisites

• Tried the most recent nightly build
• Checked if your issue is already reported.
• Answered all the questions in this template (Or provide a working crystal ball).

What happened?

Using the Electron app, built locally, I pasted the SHA256 fingerprint of my self-signed server cert into the proper field in the Settings. (Not entirely clear how the fingerprint should be formatted. Does it have colons between bytes or not, etc.?)

I always get a verification error during STARTTLS.

Based on logging I did, options.ignoreCertErrors isn't being set anywhere, so we always raise an exception and bail out of the connection before upgrading completes.

What did you expect to happen?

I expected to be able to use the fingerprint feature to get around a self-signed cert not verifying.

Which Version

• sieve dfeeac1 + local patches to debug via console logging in the Electron app
• macOS 12.6.4
• dovecot 2.3.20_1 in a FreeBSD 13.1 jail
