Bypassing Rspamd for specific emails, domains, or users requires configuring whitelisting rules and scoring adjustments in Rspamd’s configuration files. Here’s a step-by-step guide to configuring a bypass in Rspamd:

Step 1: Access the Rspamd Configuration Directory

1. Connect to your server via SSH:

sh

CopyEdit

ssh user@yourserver

2. Navigate to the Rspamd configuration directory:

sh

CopyEdit

cd /etc/rspamd/

Step 2: Whitelist an Email or Domain

To bypass Rspamd filtering for specific senders or domains:

1. Open the whitelist configuration file (create if it doesn’t exist):

sh

CopyEdit

sudo nano /etc/rspamd/local.d/whitelist_sender.map

2. Add the emails or domains you want to bypass (one per line):

pgsql

CopyEdit

user@example.com

@trusted-domain.com

3. Save and exit (CTRL + X, then Y, then Enter).

4. Now, link this whitelist to Rspamd filtering:

sh

CopyEdit

sudo nano /etc/rspamd/local.d/settings.conf

5. Add the following configuration:

yaml

CopyEdit

whitelist {

priority = “high”;

from = “/etc/rspamd/local.d/whitelist_sender.map”;

apply {

symbols_disabled = [“ALL”];

groups_disabled = [“antivirus”, “antiphishing”, “antispam”];

}

}

 6. Save and exit.

Step 3: Disable Scoring for Whitelisted Senders

If you want to ensure that whitelisted senders have zero spam score:

1. Edit the scores configuration file:

sh

CopyEdit

sudo nano /etc/rspamd/local.d/metrics.conf

 2. Add:

yaml

CopyEdit

whitelist {

id = “whitelist”;

score = -100;

description = “Whitelisted sender, bypass Rspamd checks”;

}

3. Save and exit.

Step 4: Restart Rspamd

After making changes, restart Rspamd to apply them:

sh

CopyEdit

sudo systemctl restart rspamd

Step 5: Verify the Configuration

To check if the bypass is working:

sh

CopyEdit

rspamc symbols test-email@example.com

• If the whitelisted sender is working, the spam score should be low or zero.
