##### security concerns
|
||||
The [german wikipedia tells that there are some security concern with fetchmail](https://de.wikipedia.org/wiki/Fetchmail). If in the future a customer needs to functions of fetchmail, it could be better to write a docker container for [getmail](https://en.wikipedia.org/wiki/Getmail) instead because it should be more secure.
|
||||
## Setup
|
||||
|
||||
##### workaround
|
||||
If you need to receive emails from another account this should help:
|
||||
### Fetchmail Issues
|
||||
|
||||
- Redirect to your new email account
|
||||
- Export all data from your original account
|
||||
- Import all data from your original account to your new account
|
||||
Fetchmail might not work properly with large amounts of data. For more information, refer to this [issue](https://github.com/Mailu/Mailu/issues/1719).
|
||||
|
||||
### delete data
|
||||
To delete all volumes and data execute:
|
||||
#### Deactivating Fetchmail
|
||||
|
||||
Before uninstalling Fetchmail, ensure to remove all fetched accounts from the administration panel.
|
||||
|
||||
#### Fetchmail Security Concerns
|
||||
|
||||
There are known security concerns with Fetchmail as stated in the [German Wikipedia](https://de.wikipedia.org/wiki/Fetchmail). If you require Fetchmail functions in the future, consider creating a Docker container for [Getmail](https://en.wikipedia.org/wiki/Getmail) as it is considered more secure.
|
||||
|
||||
#### Fetchmail Workaround
|
||||
|
||||
If you need to receive emails from another account, follow these steps:
|
||||
|

|
||||
3. Import all data to your new account.

|
||||
rm -vr /etc/mailu/; docker volume rm $(docker volume ls -q | grep mailu_)
|
||||
```
|
||||
Be careful!
|
||||
|
||||
### ports

||||
Keep in mind to change the conflicting ports manual.
|
||||
Execute
|
||||
### Port Management
