Subject Expressions
This list allows the configuration of subject matching expressions. When an expression matches it will perform the action specified for the expression.
The expression type shows the type of expression the matching engine will use for the entered expression.
Expressions have a built in precedence: Allow > Delete > Block > Mark > Weight
Remember that your SPAM Blocker/Action settings may globally preclude one or more of these actions.
Expression types:
Case insensitive substring
simply "match" or "sub(match)"
sub(mail) matches the phrase "Hexamail produces server software"
Case sensitive substring
"SUB(match)"
SUB(mail) does not match the phrase "HexaMail produces server software"
Case insensitive exact match
"cmp(match)"
cmp(mail) matches ONLY the entire exact string "mAil"
Case sensitive exact match
"CMP(match)"
CMP(mail) matches ONLY the entire exact string "mail"
Case insensitive word match
" match " or "word(match)"
word(mail) does not match the phrase "Hexamail produces server software" but does match the phrase "Hexamail produces mail server software"
Case sensitive word match
