IMAP Find Emails by Date

See more IMAP Examples

Explains how to find emails by date using the IMAP protocol. Rust

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let imap = chilkat::Imap::new();

// Connect to an IMAP server.
imap.set_ssl(true);
imap.set_port(993);
if imap.connect("imap.example.com").is_err() {
    println!("{}", imap.last_error_text());
    return;
}

// Login
if imap.login("myLogin", "myPassword").is_err() {
    println!("{}", imap.last_error_text());
    return;
}

// Select an IMAP mailbox
if imap.select_mailbox("Inbox").is_err() {
    println!("{}", imap.last_error_text());
    return;
}

// 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.
let on_date = "SENTON 15-Apr-2024".to_string();

// 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.
let between_dates = "SENTSINCE 12-Apr-2024 SENTBEFORE 15-Apr-2024".to_string();

// We can choose to fetch UIDs or sequence numbers.
let fetch_uids = true;

let message_set = chilkat::MessageSet::new();
if imap.query_mbx(&between_dates, fetch_uids, &message_set).is_err() {
    println!("{}", imap.last_error_text());
    return;
}

println!("{}", message_set.to_compact_string().unwrap_or_default());

// Download each email in the message set.
let email = chilkat::Email::new();
let message_count = message_set.count();
let mut i = 0;
while i < message_count {
    if imap.fetch_email(false, message_set.get_id(i), fetch_uids, &email).is_err() {
        println!("{}", imap.last_error_text());
        return;
    }

    println!("{}", email.subject());
    // ...

    i = i + 1;
}

// Disconnect from the IMAP server.
let _ = imap.disconnect().is_ok();
