After the upgrade I cannot send mail from roundcube as it seems. I get a red fault in the lower right corner where it says SMTP Error (): Authentication failed
I can send from cmdline and from my phone but not with roundcube. In /etc/postfix/main.cf I have configured a relayhost =.... if that matters. My phone is configured to connect to the mail server and not to the relay.
