Searching an IMAP mailbox for messages that match search criteria.

Chilkat Xojo Plugin Download

Xojo Plugin for Windows, Linux, Mac OS X, and ARM, ARM64

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

Dim imap As New Chilkat.Imap

// Connect to an IMAP server.
// Use TLS
imap.Ssl = True
imap.Port = 993
Dim success As Boolean
success = imap.Connect("imap.someMailServer.com")
If (success <> True) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

// Login
success = imap.Login("myLogin","myPassword")
If (success <> True) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

// Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
If (success <> True) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

Dim messageSet As Chilkat.MessageSet
// We can choose to fetch UIDs or sequence numbers.
Dim fetchUids As Boolean
fetchUids = True

// Here are examples of different search criteria:

// Return all messages.
Dim allMsgs As String
allMsgs = "ALL"

// Search for already-answered emails.
Dim answered As String
answered = "ANSWERED"

// 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.
Dim onDate As String
onDate = "SENTON 05-Mar-2007"

// 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.
Dim betweenDates As String
betweenDates = "SENTSINCE 01-Mar-2007 SENTBEFORE 05-Mar-2007"

// Another example of AND: find all unanswered emails
// sent after 04-Mar-2007 with "Problem" in the subject:
Dim complexSearch1 As String
complexSearch1 = "UNANSWERED SENTSINCE 04-Mar-2007 Subject ""Problem"""

// Find messages with a specific string in the body:
Dim bodySearch As String
bodySearch = "BODY ""problem solved"""

// Using OR.  The syntax is OR <criteria1> <criteria2>. 
// The "OR" comes first, followed by each criteria.
// For example, to match all emails with "Help" or "Question" in the subject.
// You'll notice that literal strings may be quoted or unquoted.
// If a literal contains SPACE characters, quote it:
Dim orSearch As String
orSearch = "OR SUBJECT Help SUBJECT Question"

// ----------------------------------------------
// Strings are case-insensitive when searching....
// ----------------------------------------------

// Find all emails sent from yahoo.com addresses:
Dim fromSearch As String
fromSearch = "FROM yahoo.com"
// Find all emails sent from anyone with "John" in their name:
Dim johnSearch As String
johnSearch = "FROM John"

// Find emails with the RECENT flag set:
Dim recentSearch As String
recentSearch = "RECENT"

// Find emails that don't have the recent flag set:
Dim notRecentSearch As String
notRecentSearch = "NOT RECENT"
// This is synonymous with "OLD":
Dim oldSearch As String
oldSearch = "OLD"

// Find all emails marked for deletion:
Dim markedForDeleteSearch As String
markedForDeleteSearch = "DELETED"

// Find all emails having a specified header field with a value
// containing a substring:
Dim headerSearch As String
headerSearch = "HEADER DomainKey-Signature paypal.com"

// Find any emails having a specific header field.  If the 
// 2nd argument to the "HEADER" criteria is an empty string,
// any email having the header field is returned regardless
// of the header field's content.
// Find any emails with a DomainKey-Signature field:
Dim headerExistsSearch As String
headerExistsSearch = "HEADER DomainKey-Signature """""

// Find NEW emails: these are emails that have the RECENT flag
// set, but not the SEEN flag:
Dim newSearch As String
newSearch = "NEW"

// Find emails larger than a certain number of bytes:
Dim sizeLargerSearch As String
sizeLargerSearch = "LARGER 500000"

// Find emails marked as seen or not already seen:
Dim seenSearch As String
seenSearch = "SEEN"
Dim notSeenSearch As String
notSeenSearch = "NOT SEEN"

// Find emails having a given substring in the TO header field:
Dim toSearch As String
toSearch = "TO support@chilkatsoft.com"
// A more long-winded way to do the same thing:
Dim toSearch2 As String
toSearch2 = "HEADER TO support@chilkatsoft.com"

// Find emails smaller than a size in bytes:
Dim smallerSearch As String
smallerSearch = "SMALLER 30000"

// Find emails that have a substring anywhere in the header
// or body:
Dim fullSubstringSearch As String
fullSubstringSearch = "TEXT ""Zip Component"""

// Pass any of the above strings here to test a search:
messageSet = imap.Search(orSearch,fetchUids)
If (imap.LastMethodSuccess = False) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

// Fetch the email headers into a bundle object:
Dim bundle As Chilkat.EmailBundle
bundle = imap.FetchHeaders(messageSet)
If (imap.LastMethodSuccess = False) Then

    System.DebugLog(imap.LastErrorText)
    Return
End If

// Display the Subject and From of each email.
Dim i As Int32
i = 0
While i < bundle.MessageCount
    Dim email As Chilkat.Email
    email = bundle.GetEmail(i)

    System.DebugLog(email.GetHeaderField("Date"))
    System.DebugLog(email.Subject)
    System.DebugLog(email.From)
    System.DebugLog("--")

    i = i + 1
Wend

// Disconnect from the IMAP server.
success = imap.Disconnect()
