You could remove domains from daily.pdb/whitelist all mails that contain
certain domains.

The problem is that amazon/ebay is a very likely target for phishing, so
if you remove these domains entirely you will miss some phishing.

Here is an example daily.wdb entry (it is a regular expression for the 2
sides of the link):
X:.+\.amazon\.(at|ca|co\.uk|co\.jp|com|de|fr)([/?].*)?:(.+\.)?amazon\.com([/?].*)?:17-

And here is another one:
M:chase.com:jpmchase.com

You can see all the current .wdb entries by downloading daily.cvd, and
running sigtool --unpack-current daily.

The format of .wdb is documented in docs/phishsigs_howto.pdf

You can start by adding just the domain names to the .wdb, i.e.:
M:amazon.ca:OTHERDOMAIN

where OTHERDOMAIN is the displayed domain name (the part between
<a></a>), assuming amazon.ca is the domain in the href.
