What is Blocklisting
Blocklisting is when you provide an email address or regular expression that, if the sender (from: address) matches, will be prevented from being processed. If a blocklisted entry is present, everything else is deemed good.

The address field is regular expression sensitive. Note that the '*' character has special meaning in regexp, it means zero or more of the preceding character, not any character. The dot '.' means any character except line, hence match all is '.*'. Therefore, it is best to escape dots with a backslash '\.', otherwise if left as a dot there is the chance that an unexpected address matches the regexp. For example: "jira@company.co.uk" would also allow the address "jira@companyaco.uk". |
