having installed successfully yunohost on a raspberry 1 B+, and having installed rainloop as a mail , i am facing the following problems:
- I am receiving every few minutes the same message: ; Communication with server failed: timed out
Unable to update IP address on DynDNS
- I can receive emails but not sending.
- I cannot install roundcube (even after having uninstalled rain loop).
Any hint ? Thanks in advance
