Criterion constructor functions for the SAVEDATE extension (RFC 8514)

Build the SAVEDBEFORE, SAVEDON, and SAVEDSINCE search keys, which compare the date a message was saved into the mailbox (the SAVEDATE attribute) rather than its internal date or its Date: header. They are to be combined with AND and OR and passed to ImapCon$search(). The server must advertise the SAVEDATE capability.

Usage

saved_before(date_char, negate = FALSE)

saved_since(date_char, negate = FALSE)

saved_on(date_char, negate = FALSE)

Arguments

date_char

A character string with a date in the IMAP format DD-Mon-YYYY, e.g. "17-Apr-2019".

negate

If TRUE, negates the search and seeks for "NOT SEARCH CRITERIA". Default is FALSE.

Value

A character string with the search criterion.

Examples

if (FALSE) { # \dontrun{
con$select_folder(folder = "INBOX")
# messages saved into the folder during the last ingestion day
res <- con$search(request = saved_since(date_char = "27-Aug-2026"))
} # }
