Description of my issue

I have a secondary domain set up on my Yuno host. All works well with domain #1.

For domain #2, I cannot get iOS Mail client email app to connect.

When I set up a new Mail account in iOS and point it to domain #2, it generates a certificate error because Yunohost seems to use the certificate for the primary domain #1, not for my secondary domain #2.

What is the right way to set up email for secondary domain on a Yunohost installation?

I think it’s fix in YunoHost 11

Thanks @ljf, I managed to install the Yunohost 11 update, and the email on my secondary domain appears to now be working as expected!
