Is it good practice to consolidate rules?

I’ve got over 15K rules in my blocklist and 48K in my allowlist and am wondering if I should try consolidating these rules. Does anyone else do this? I reckon that filtering might run faster?

I also have a ton of rules in each list that aren’t enabled. Is there any risk to deleting rules that aren’t enabled?

I think that would take you a lot of time and make the filtering slower.

Yes. The disabled rules are recording the fact that you don’t want that rule. If you delete it, when you train a message SpamSieve might end up recreating the unwanted rule in an enabled state.

Regarding disabled rules, I have these on my blacklists. I didn’t set them up!
What do they refer to?

  1. Body (any part of the text) : Matches the regular expression <IMG[^>]"cid:[^>]>

  2. From (name) Is equal to

SpamSieve ships with a small number of built-in blocklist rules. The first one is for matching spams with a certain type of inline image. The second one is included as disabled to prevent SpamSieve from auto-creating an unwanted rule when you train a message with a missing name.

Which image ? Can you explain it to me?

An image that’s attached to the e-mail itself (rather than linked to a server, which is what most good e-mails do) and displayed using HTML.

Thank you for your advice - that saves me a lot of work and a lot of risk!
