IMAP Download All Email One at a Time

Demonstrates how to download every email in an IMAP mailbox one at a time as a MIME string or as an email object. (The MIME contains the full contents of the email including all attachments.) PowerBuilder

integer li_rc
integer li_Success
oleobject loo_Imap
integer li_BUid
string ls_MimeStr
integer i
integer n
oleobject loo_Email

li_Success = 0

loo_Imap = create oleobject

    destroy loo_Imap

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

// Connect to an IMAP server.
// Use TLS
loo_Imap.Ssl = 1
loo_Imap.Port = 993
li_Success = loo_Imap.Connect("imap.example.com")
if li_Success = 0 then
    Write-Debug loo_Imap.LastErrorText

// Select an IMAP mailbox
li_Success = loo_Imap.SelectMailbox("Inbox")
if li_Success = 0 then
    Write-Debug loo_Imap.LastErrorText
    destroy loo_Imap

// Once the mailbox is selected, the NumMessages property
// will contain the number of messages in the mailbox.
// You may loop from 1 to NumMessages to
// fetch each message by sequence number.

    // Download the email by sequence number.

    // ... your application may process each MIME string...
next

// An alternative is to download each email in the form of an
// email object, like this:
loo_Email = create oleobject
li_rc = loo_Email.ConnectToNewObject("Chilkat.Email")

for i = 1 to n

    // Download the email by sequence number.
    li_Success = loo_Imap.FetchEmail(0,i,li_BUid,loo_Email)

    // ... your application may process the email object...

next

// Disconnect from the IMAP server.
