I was planing to migrate calendar/contact/mail from sogo to nextcloud. I tested the rainloop integration and this was satisfying. Unfortunately, I read that the rainloop integration is deprecated and will not work with the next version of nextcloud due to changes in the API.
I’m looking to find a new webmail replacement. The official webmail app is interesting. I like how it is completely integrated to nextcloud, but it lacks important features like managing sieve filters and signature. Roundcube is nice, but seem like there is no way to integrate it to nextcloud (I would like to avoid to have to authenticate twice).
if you are using a webmail with nextcloud, what are you using?
