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

set imapSrc = Server.CreateObject("Chilkat.Imap")

' Connect to our source IMAP server.
success = imapSrc.Connect("imap.example.com")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( imapSrc.LastErrorText) & "</pre>"
    Response.End
End If

' Login to the source IMAP server
success = imapSrc.Login("admin@chilkatsoft.com","myPassword")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( imapSrc.LastErrorText) & "</pre>"
    Response.End
End If

set imapDest = Server.CreateObject("Chilkat.Imap")

' Connect to our destination IMAP server.
success = imapDest.Connect("mail.example-code.com")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( imapDest.LastErrorText) & "</pre>"
    Response.End
End If

' Login to the destination IMAP server
success = imapDest.Login("myLogin","myPassword")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( imapDest.LastErrorText) & "</pre>"
    Response.End
End If

' Select an IMAP mailbox on the source IMAP server
success = imapSrc.SelectMailbox("Inbox")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( imapSrc.LastErrorText) & "</pre>"
    Response.End
End If

' After selecting a mailbox, the NumMessages property will
' be updated to reflect the total number of emails in the mailbox:
Response.Write "<pre>" & Server.HTMLEncode( imapSrc.NumMessages) & "</pre>"

' The emails in the mailbox will always have sequence numbers
' ranging from 1 to NumMessages.

' This example will copy the first 10 messages using sequence numbers
set sbMime = Server.CreateObject("Chilkat.StringBuilder")

For seqNum = 1 To 10
    sbMime.Clear 
    success = imapSrc.FetchSingleAsMimeSb(seqNum,0,sbMime)
    If (success = 0) Then
        Response.Write "<pre>" & Server.HTMLEncode( imapSrc.LastErrorText) & "</pre>"
        Response.End
    End If

    success = imapDest.AppendMimeWithFlagsSb("Inbox",sbMime,0,0,0,0)
    If (success = 0) Then
        Response.Write "<pre>" & Server.HTMLEncode( imapDest.LastErrorText) & "</pre>"
        Response.End
    End If

Next

' Disconnect from the IMAP servers.
success = imapSrc.Disconnect()
success = imapDest.Disconnect()
