Add emails to denylist without directly editing procmail

guberman

Is there any way that I could add email senders to a personal denylist without directly editing procmail? I'm thinking it'd be nice to forward a message to something like denylist@mydomain.com and have it automatically added.

If the procmail file is somewhere I can access then I can probably write a script for it myself (or find one someone else has written), but I was wondering if there was already a solution for something like this.

Thanks!

guberman at this time all server-side mail filtering must be done via the procmailrc setting for your mailbox.

You do not have direct access to the file, but if you want to script your procmailrc updates you can so so via the mailuser/update method in the Opalstack REST API.

Here's an example in Python that will apply a set of procmail rules for all of the mailboxes on your account:

import requests

TOKEN = "YOUR_API_TOKEN"

headers = {"Authorization": f"Token {TOKEN}", "Content-type": "application/json"}

procmail = """
YOUR
PROCMAIL
RULES
"""

mailboxes = requests.get(
    "https://my.opalstack.com/api/v1/mailuser/list/", headers=headers
)

for mb in mailboxes.json():
    payload = [{"id": mb["id"], "procmailrc": procmail}]
    r = requests.post(
        "https://my.opalstack.com/api/v1/mailuser/update/",
        headers=headers,
        json=payload,
    )

Thanks @sean ! I didn't know about the Opalstack REST API. That's exactly what I needed. I can combine that with a procmail rule that calls the Python script whenever a message is sent to spam@mydomain.com, and it'll be exactly what I want.
