[New Plugin] Configure and use fetchmail from the WebApp

fbartels

@mcostan yes, we have that already on our agenda. As a matter of fact I just added some more links and made it public. You can find it at https://stash.z-hub.io/projects/COM/repos/projects-and-resources/browse

@olia would you be so kind to run through the explained workflow in https://stash.z-hub.io/projects/COM/repos/projects-and-resources/browse/CONTRIBUTING.md and add your project? I am interested if the instructions are clear enough or need to be clarified/simplified. Thanks!

@fbartels
I’ve read the document, and followed it (waiting to hear back for write access to the repo).
Also the instructions are clear enough.

@olia thanks, I just replied to your request.

Hi,
I am not a very skilled Linux user, but i come as far as getting the Fetchmail plugin show up as a plugin. But as soon as i go to the Options in Kopano, i get a Http 500 internal server error as long as the plugin is enabled. So i must be doing something wrong. I’ll try to describe what i have done:

I use a Univention debian distro in a virtual machine. I installed Kopano-core & Kopano-webapp & got that working, including sending mail via a smart relay host.

Installed Requierements ( i think)

fetchmail: dpkg -l | grep fetchmail shows it as installed
libproc-daemon-perl: installed via apt-get
MTA on the host machine (postfix): is working, i can send mail
Database to store account informations (At the moment only ‘mysql’ is supported): i did not take specific action on this, i presume Kopano-core install took care of this?

I was able to download, install & activate the plugin; it shows up in the options in kopano-webapp.

I copied the example.config.php in the <kopano-webapp>/plugins/fetchmail folder to config.php ** in the same folder ** and customized the ‘changethis!’ part in define(‘PLUGIN_FETCHMAIL_PASSWORDS_AES_KEY’, “changethis!”)

i did not create a user to run the fetchmail daemon (i found the (default: fetchmail/nogroup) )
i did not Manual: Set the rights for the home directory to 600.
i did not Edit the <kopano-webapp>/plugins/fetchmail/php/daemon/kopano_fetchmail.pl if you used non-standard options.

i Started the daemon with perl kopano_fetchmail.pl --start and no errors where shown.

I still have to create a startup script. (see kopano_fetchmail.service.example for a systemd config).

I did not make any symlinks as previously posted?

Thanks in advance

@pwhooftman
Update: i reinstalled phpmyadmin, and now the error states: Cannot connect to database. So, progress :-)

But if i look in phpmyadmin no fetchmail user or table(s) for the plugin are present. Do i have to set up the mysql for the plugin myself (user, tables, etc) , or is that something the daemon should take care of?

pwhooftman

Update: got it working

Fetchmail was not installed yet :-|
set mysql root users password
changed mysql user & password to root in config.php

ckraut

Do you think it would be possible to have a plugin for the the other direction so that it’s possible to set for each User Account several smtp Server in the same way as you made it possible for the fetchmail function.

I have install the Plugin.

Can Anyone help me???

its older but here is my how to for Ubuntu 18.04

Install the Requirements.

apt install fetchmail libproc-daemon-perl

by installing fetchmail you see the following strings like this:
Adding system user fetchmail' (UID 119) ... Adding new user fetchmail’ (UID 119) with group nogroup' ... Creating home directory /var/lib/fetchmail’ …

Download and unzip the fetchmail-1.0.zip to the ‘plugins’ folder in your kopano-webapp installation (default:
/usr/share/kopano-webapp/plugins/

cd /tmp
wget https://github.com/olia-dev/kopano-webapp-fetchmail/archive/master.zip
unzip master.zip -d /tmp/fetchmail
cd /tmp/fetchmail/kopano-webapp-fetchmail-master/builds
unzip fetchmail-1.0.2.zip -d /usr/share/kopano-webapp/plugins/
cd /usr/share/kopano-webapp/plugins/fetchmail
mv example.config.php /etc/kopano/webapp/config-fetchmail.php
ln -s /etc/kopano/webapp/config-fetchmail.php config.php

Create Fetchmail User & Database in MYSQL

sudo mysql -u root -p 

CREATE DATABASE kopano_fetchmail DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
CREATE USER 'kopano_fetchmail'@'localhost' IDENTIFIED BY 'SeCrEtPasSwOrD';
GRANT ALL PRIVILEGES ON kopano_fetchmail.* TO 'kopano_fetchmail'@'localhost';
FLUSH PRIVILEGES;

quit

Edit your settings:

nano /etc/kopano/webapp/config-fetchmail.php

Edit if you used non-standard options (none in my case)

nano /php/daemon/kopano_fetchmail.pl

Start the daemon with

perl /usr/share/kopano-webapp/plugins/fetchmail/php/daemon/kopano_fetchmail.pl --start

Create System startup script. (see kopano_fetchmail.service.example for a systemd config).
use this example to /etc/systemd/system/

mv /usr/share/kopano-webapp/plugins/fetchmail/kopano_fetchmail.service.example /usr/share/kopano-webapp/plugins/fetchmail/kopano_fetchmail.service

ln -s /usr/share/kopano-webapp/plugins/fetchmail/kopano_fetchmail.service /etc/systemd/system/kopano_fetchmail.service

The system service script shows at following

nano /etc/systemd/system/kopano_fetchmail.service```

systemctl enable kopano_fetchmail.service

Run the following systemd command to start the fail2rest service

systemctl start kopano_fetchmail.service

Verify that the fail2rest service it is active and running

systemctl status kopano_fetchmail.service
