S: "SIEVE" "fileinto reject envelope vacation imapflags notify
subaddress relational comparator-i;ascii-numeric regex"


I notice the IETF has multiple versions of many of these, and one of

Any way to tell more precisely what semantics I'm getting (that is,
any way faster than reading the code or experimentation)?
