get_min_id: Get Minimum Message ID in a Mailbox

Description

Get the smaller (minimum) message id in a Mailbox, considering messages with a specific flag.

Usage

get_min_id(imapconf, by = "MSN", flag, retries = 2)

Arguments

imapconf

An object of class imapconf generated with configure_imap and with a mbox item added after a mailbox selection with select_mailbox.

by

Which id (MSN or UID) to use when searching for messages. "MSN" or message squence number is a message's relative position to the older message in the mailbox. It may change after deleting or moving messages. For instance, if a message is deleted, message sequence numbers are reordered to fill the gap. "UID" or unique identifier is always the same during the life cycle of a message. Default is "MSN".

flag

A string specifying the flag to be used for filtering messages. Use flag_options to list the common flags used by IMAP servers. Default is NULL.

retries

Number of attempts to connect and execute the command. Default is 2.

Value

A numeric vector of length 1 indicating the minimum id.
