If the spamcop_uri_limit is set (which it is by default) and the number of URLs in the message exceeds this limit, the URLs are shuffled and testing is done only up to the limit. These are typically just http, https, and ftp. This currently only checks URIs that support methods for host. If the URL's host is in the blacklist, then the test is an immediate hit. If the URL's host appears in the whitelist, then the test is an immediate miss. The first checks that SpamCopURI does is against the whitelist/blacklist. The wildcarding is identical to what is used for the core whitelists that ship with SA. You may blacklist/whitelist domains by using the whitelist_spamcop_uri or blacklist_spamcop_uri.

A spamassassin expression begins with / ends with / and the i means case insensitive. Edit this list to include any TLD you typically receive mail from. Part 2: (com|org|net|mil|edu) is the list of TLDs we do not penalize. would be caught because ! is not allowed in a hostmame. Part 1: catches a legit hostname (pany) without the TLD (com, org, etc).

SpamAssassin runs hundreds of tests, and they all have a subtle effect on the final spam score. We want to reduce spam, but still accept/deliver legitimate mail from these TLDs. Your additions should load last, so we’ll call this new filter: z_tld.cf When the same setting is repeated, the last occurrence wins. cf and are processed in alphabetical order. Within this directory, you can customize SpamAssassin with configuration files for filters, whitelists, blacklists, score overrides and more. The local configuration for SpamAssassin is stored in this directory: You also should be familiar with editing plain text configuration files. Important: This filter is not for everyone and you should adjust for best results considering your mail traffic and typical senders.
