# 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
$imap.Ssl = $true
$imap.Port = 993
$success = $imap.Connect("imap.someMailServer.com")
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# Login
$success = $imap.Login("myLogin","myPassword")
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# Select an IMAP mailbox
$success = $imap.SelectMailbox("Inbox")
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# 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.

$bUid = $false

$n = $imap.NumMessages
for ($i = 1; $i -le $n; $i++) {

    # Download the email by sequence number.
    $mimeStr = $imap.FetchSingleAsMime($i,$bUid)

    # ... your application may process each MIME string...
}

# An alternative is to download each email in the form of an
# email object, like this:

for ($i = 1; $i -le $n; $i++) {

    # Download the email by sequence number.
    $email = $imap.FetchSingle($i,$bUid)

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

}

# Disconnect from the IMAP server.
$success = $imap.Disconnect()
