Installed iRedMail on Ubuntu Server in February 2016 and noticed an error when trying to send a message via Roundcube:
SMTP error (451): Unable to add recipient “Email” (4.3.5 Server configuration problem)
I checked if iredapd is running:
telnet localhost 7777
It turned out that it was not running because the response from telnet was displayed:
Unable to connect to remote host: Connection refused
Tried to run:
sudo /etc/init.d/iredapd start
To which he received the answer:
ImportError: No module named ldap
I installed the module with the command:
sudo apt-get install python-ldap
Execute the commands:
sudo -i
cd /opt/iredapd/
find . -name '*pyc' | xargs rm -f {}
Now restart the service:
sudo service iredapd restart
Done, there is no error.
