' In the IMAP (Internet Message Access Protocol) protocol, criteria strings are used to search for emails matching specific criteria on the mail server. 
' When searching for emails by date, you can use criteria strings to specify the date range you're interested in.
' 
' IMAP provides several options for searching emails by date using criteria strings. Here are the commonly used ones:
' 
' 1. BEFORE: Searches for emails sent before a specific date.
'    Example: BEFORE 01-Apr-2022
' 
' 2. ON: Searches for emails sent on a specific date.
'    Example: ON 01-Apr-2022
' 
' 3. SINCE: Searches for emails sent after a specific date.
'    Example: SINCE 01-Apr-2022
' 
' 4. SENTBEFORE: Searches for emails whose date header (sent date) is before a specific date.
'    Example: SENTBEFORE 01-Apr-2022
' 
' 5. SENTON: Searches for emails whose date header (sent date) is on a specific date.
'    Example: SENTON 01-Apr-2022
' 
' 6. SENTSINCE: Searches for emails whose date header (sent date) is after a specific date.
'    Example: SENTSINCE 01-Apr-2022
' 

' 
' The date format used in IMAP criteria strings is typically a specific format like "DD-Mon-YYYY" (e.g., "01-Apr-2022"), but some servers may also accept other formats 
' such as "YYYY-MM-DD". It's essential to check the documentation or specifications of the IMAP server you're working with to ensure compatibility with the 
' date format you're using.
' 
' By combining these date criteria strings with other search criteria (such as sender, recipient, subject, etc.), 
' you can effectively filter and retrieve emails based on various conditions.
' 

' Search for messages on a specific date.
' The date string is DD-Month-YYYY where Month is
' Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, or Dec.
onDate = "SENTON 15-Apr-2024"

' Search for messages between two dates.  SENTBEFORE
' finds emails sent before a date, and SENTSINCE finds
' email sent on or after a date.  The "AND" operation
' is implied by joining criteria, separated by spaces.
betweenDates = "SENTSINCE 12-Apr-2024 SENTBEFORE 15-Apr-2024"

' We can choose to fetch UIDs or sequence numbers.
fetchUids = 1

set messageSet = CreateObject("Chilkat.MessageSet")
