I really love K9 Mail! Thanks for this great app!
Can I make K9 Mail only accept a certain certificate (identified by its fingerprint) for IMAPS instead of having it accept a certificate from any dubious country CA?
I considered using a self-signed certificate for my IMAPS server. Then K9 Mail would save the fingerprint of the self-signed certificate to trust it.
But I suspect, if some day my server would show up with a certificate signed by an “official” CA from anywhere in the world, K9 mail would accept that as well. Although I wanted to use only my self-signed certificate. Is that right?
Are you aware of ways to limit “trust” of K9 Mail to a certain CA or a certain certificate fingerprint?
Thanks a lot and keep up the good work!
