I try to do a bit more advanced rules in the email blacklist in Spamassassin but I cant find a list of all possible rules.
Do any of you know of any comprehensible list of all wildcard characters that are allowed.
For example can I do the following
what is possible here is there any list of possible combinations to filter there domains with constant changing numbers or 1 letter differences.
the email comes from number@domainnotices####.com or net etc.
Thank you for any assistance on this.
