Hi all,

Since IOS 13 update(yesterday), I receive "cannot verify server identity" when trying to get/send emails.

My dovecot certificate is valid and generated using mkcert.sh in /usr/doc/dovecot-2.2.33.2/ and it worked until now on IOS devices and still working on all other non IOS devices.

Any ideea how to fix it?

I would recommend using lets encrypt certificates, as with self signed certificates you will always receive warnings...
You can use certbot available on SMS repository..

You can otherwise install certificate on IOS and create a profile for it and mark it as trusted..

Hi,

I've tried to use certbot but can't resolve:
