SPAM EXPERTS: Is there a block list rules limitation?
Is there a block list rules limitation? Should I use one rule with one keyword like (?i)(word) oder would it be better to write keywords with RegEx in one rule? (? i) (Posted on Sunday) | (Order confirmed) | (Due to a problem sign activity) | (Summary) I tried this, but this is a dangegous option, when in the RegEx rule is an syntax error. https://documentation.n-able.com/spamexperts/userguide/email/Content/B_Admin%20Level/incoming-filtering/adv-inc-blocklist-rule-examples.htm
