README.md

This is a fetchmail module for [NethServer 8](https://github.com/NethServer/ns8-core).
 
## Install
 
Instantiate the module with:
 
    add-module ghcr.io/mrmarkuz/fetchmail:latest 1
 
The output of the command will return the instance name.
Output example:
 
    {"module_id": "fetchmail1", "image_name": "fetchmail", "image_url": "ghcr.io/mrmarkuz/fetchmail:latest"}
 
## Configure
 
In the app settings page just enter a hostname and click save to start the service. The hostname is available as environment variable MAIL_HOST in the container and the user environment.
 
## Setup
 
Enter the environment (in this example the instance is named fetchmail1)
 
    runagent -m fetchmail1
 
You'll find 2 directories `fetchmail` and `cron` that point to the container directories `/etc/fetchmail` and `/etc/cron.d` so you could put your config files there.
 
There's another directory `log` that maps `/var/log` in the container to be able to check the log file(s).
 
An example cronjob file to put to `cron/examplecronjob` that runs fetchmail every 5 minutes:
 
```
*/5 * * * * root /usr/bin/fetchmail -d0 -v -f /etc/fetchmail/fetchmailrc > /var/log/fetchmail.log
```
 
An example fetchmail config file to put to `fetchmail/fetchmailrc`:
 
```
set no bouncemail
set no spambounce
set properties ""
 
poll pop.server tracepolls proto pop3 uidl auth password port 995 timeout 60
    user "<USER_NAME>" password "<PASSWORD>" ssl keep is <localmailuser@localmailserver.com> smtphost <Neth_IP>
```
 
This one did work for IMAP on port 143:
 
```
#   IMAP
poll mrmarkuz.domain.tld proto imap port 143
    user "<USER_NAME>" password "<PASSWORD>" keep is "markus@ns8test.com" here smtphost <Neth_IP>
```
 
This one did work for IMAPS on port 993:
 
```
#   IMAPS
poll mrmarkuz.domain.tld proto imap port 993
    user "<USER_NAME>" password "<PASSWORD>" ssl keep is "markus@ns8test.com" here smtphost <Neth_IP>
```
 
The fetchmailrc file needs to have permission 700.
 
    chmod 700 fetchmail/fetchmailrc
 
After setting a cronjob and fetchmail config the mails should be fetched as given in your config. The mails are checked by rspamd.
 
## Uninstall
 
To uninstall the instance:
 
    remove-module --no-preserve fetchmail1
