NethServer Version: 7
OK, this may not be bug in terms of an error as I suppose that the modules works as expected. IMO this is more a kind of technical unexpected behavior causing confusion for the user / admin. I kindly suggest to alter within a future update:
I use Nethserver email as an internal smarthost aka “Allow relay from trusted networks” for the following purpose:
Submit notification emails from green network servers to the admin, e.g. backup accomplish from DMS server or S.M.A.R.T reports from Proxmox VE server etc. Also my OKI MFP (“multi functinal printer”) can send scanned PDF files by eMail via smarthost.
Most stuff is send directly to me (email@example.com). Quite strange to me was the fact that rspamd marks this email as spam. I thought this was processed during recieving process for my inbox.
I did not really care as I manually moved it from Junk folder to my inbox counting on the training effect. This was annoying, but not serious. For some cases I even added specific “Rules by mail address->allow”. Anyway I found that unnecessary for email from a source within green network.
Today I noticed something completly (unsatisfactory) different. I have scanned a document on my OKI MPF and sent it directly to my business email adress (firstname.lastname@example.org). The email subject was rewritten to “[+++SPAM+++]” using the corresponding text from Nethserver email settings. This is not to nice as the recipient recieves an email marked as spam from the sending server .
Just to make sure: The process was definitly triggered by Nethserver / rspamd. The company uses a different, external spam service provider. Also, the company has a different annotation for marking spam. In this case only the rspamd text [+++SPAM+++] was added…
TIA for for considering
