Thank you Adfeno, Sasaki, fbit and everyone!I have not been able to send emails from my Openmailbox and RiseUp accounts for months. But now I have downgraded Icedove with
sudo apt-get install icedove=31.8.0-1~deb7u1+7.0trisquel2 and it works!I hope the ticket Mzee opened gets solved so that we can update the software when needed.
