Rainloop cannot send messages after upgrade to Yunohost 3.2 (from 2.7.14)


since I upgraded from 2.7.14 to 3.2, Rainloop can no more send emails. When trying to do so, I have a “Server Unreacheable” message.

However, I can send e-mails from a client like thunderbird and receive e-mails with Rainloop.

Any idea how to investigate that issue?

I have a problem when I want to log in with the admin account. No password works (admin and root).

Do you have an idea of ​​which password to enter ?

Thanks in advance for your help
