GNU libmu_sieve supports the following built-in comparators:
i;octetThis comparator simply compares the two arguments octet by octet
i;ascii-casemapIt treats uppercase and lowercase characters in the ASCII subset of UTF-8 as the same. This is the default comparator.
i;ascii-numericTreats the two arguments as ASCII representation of decimal numbers and compares their numeric values. This comparator must be explicitly required prior to use.
