What's the scope of wildcards for whitelists/blacklists?

[Kent Brockman]

As per the docs at Spam Filters - Version 72 Documentation - cPanel Documentation, you specify what wildcards can be used. That's ok.

But will it work to whitelist something like *@paypal.*?
Cause I need to whitelist, i.e., use cases like *@paypal.com, *@paypal.com.ar and *@paypal.es. Should it work or I need to add it one by one?

Thanks in advance.

Hi @Kent Brockman


*@paypal is usable to whitelist this is noted in the documentation you linked as well:

Note:

When you add addresses to the whitelist, use * as a wildcard to represent multiple characters and ? to represent a single-character wildcard. The following examples demonstrate how to properly use wildcards in the whitelist:

• [email protected] — Whitelists a single email address.
• *@example.com — Whitelists all of the addresses at example.com.
• [email protected] — Whitelists a single character in an address at example.com (for example, [email protected], but not [email protected]).

Hello Lauren. It's not completely or explicitly defined. I'm talking about putting the asterisk both at the beginning and at the end of the string, like in *@paypal.* , while the documentation talks about putting it only at the beginning.
So, should it work? Have you tested it?

Hi @Kent Brockman


It's not explicitly listed as something that will be recognized but I don't see any indication that it wouldn't work. I have not tested it though.

Maybe nobody thought of such an use case before Can you test it please or reach any of the dev people to confirm for yes or not?

Hi @Kent Brockman

It appears to work, I tested this from a domain that for all purposes should have been flagged as spam and got the following:

2019-04-16 13:41:26 1hGT1K-000940-4R H=mtestserverhostname (centos6.11-78-0-11.tld) [IPREMOVED]:34967 Warning: "SpamAssassin as MYUSER detected message as NOT spam (-90.3)"

The same message sent without the whitelist rule added comes up as definite spam:

2019-04-16 13:44:37 1hGT4O-00098w-Se H=mytestserverhostname (centos6.11-78-0-11.tld) [IPREMOVED]:55602 Warning: "SpamAssassin as myuser detected message as spam (10.5)"

Awesome, thanks a lot for the testing!!
Hope you can consider adding the example to the docs for better clarification.
Thanks!
