I have been using Disroot as my primary email ever since openmailbox.org stopped. I am very grateful for Disroot’s service and I occasionally donate to them.

Recently, my Disroot inbox has been flooded with spam. On an average day, I used to receive around 90% spams on entire email count. However, the situation has improved since then. I contacted the Disroot team, and they informed me that they are aware of the situation and planning to migrate to Rspamd from Spamassassin.

I don’t know whether they deployed Rspamd, even if so that only going to process incoming mails, I am looking for a way to identify spams and purge that are already entered my Imap folders.

Later I found this script nh2/rspamd-move[1], which seems fit my need.

I made couple of trivial changes in the script for my use case. I wasn’t sure of directly running this on my Mail/ dir, so I cloned my entire local mail directory to another directory and made available to podman container where the script and rspamd instance exist. I trained rspamd from the /Spam. Later, I manually moved couple of mails to /spam folder/. I requested friends to share their spam folder in the #debian-in channel, but that didn’t happen :P

$podman run -it --mount
type=bind,source=/home/abhijith/$MAILS/,target=/container-mail-clone
id:latest
$script.py

(It took some time since I have around 10000+ emails)

Wow, it was quite a successful attempt, I was able to catch most of it and move to spam/ and couple of false positive in a different folder. Now I want to do the same in the actual maildir yet very skeptical. While going through the cloned folder with mutt -f I remembered that the mails are already indexed by notmuch.

So all I need to do is operate tagging and deletion with notmuch and it will be synced back to the original mail dir. Ta-da. I cleaned by Inbox.
