## Custom reject messages
The default spam reject message can be changed by adding a new file `data/conf/rspamd/override.d/worker-proxy.custom.inc` with the following content:
```
reject_message = "My custom reject message";
```
Save the file and restart Rspamd: `docker-compose restart rspamd-mailcow`.
While the above works for rejected mails with a high spam score, global maps (as found in "Global filter maps" in /admin) will ignore this setting. For these maps, the multimap module in Rspamd needs to be adjusted:
1. Open `{mailcow-dir}/data/conf/rspamd/local.d/multimap.conf` and find the desired map symbol (e.g. `GLOBAL_SMTP_FROM_BL`).
2. Add your custom message as new line:
```
GLOBAL_SMTP_FROM_BL {
type = "from";
message = "Your domain is blacklisted, contact postmaster@your.domain to resolve this case.";`
map = "$LOCAL_CONFDIR/custom/global_smtp_from_blacklist.map";
regexp = true;
prefilter = true;
action = "reject";
}
```
3. Save the file and restart Rspamd: `docker-compose restart rspamd-mailcow`.
## Whitelist specific ClamAV signatures
You may find that legitimate (clean) mail is being blocked by ClamAV (Rspamd will flag the mail with `VIRUS_FOUND`). For instance, interactive PDF form attachments are blocked by default because the embedded Javascript code may be used for nefarious purposes. Confirm by looking at the clamd logs, e.g.:
