How to Copy IMAP Mail to another IMAP Server

Demonstrates how to copy the entire contents of an IMAP mailbox to another IMAP server. Ruby

require 'chilkat'

success = false

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

imapSrc = Chilkat::CkImap.new()

#  Connect to our source IMAP server.
success = imapSrc.Connect("imap.example.com")
if (success == false)
    print imapSrc.lastErrorText() + "\n";
    exit
end

#  Login to the source IMAP server
success = imapSrc.Login("admin@chilkatsoft.com","myPassword")
if (success == false)
    print imapSrc.lastErrorText() + "\n";
    exit
end

imapDest = Chilkat::CkImap.new()

#  Connect to our destination IMAP server.
success = imapDest.Connect("mail.example-code.com")
if (success == false)
    print imapDest.lastErrorText() + "\n";
    exit
end

#  Login to the destination IMAP server
success = imapDest.Login("myLogin","myPassword")
if (success == false)
    print imapDest.lastErrorText() + "\n";
    exit
end

#  Select an IMAP mailbox on the source IMAP server
success = imapSrc.SelectMailbox("Inbox")
if (success == false)
    print imapSrc.lastErrorText() + "\n";
    exit
end

#  After selecting a mailbox, the NumMessages property will
#  be updated to reflect the total number of emails in the mailbox:
print imapSrc.get_NumMessages().to_s() + "\n";

#  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
sbMime = Chilkat::CkStringBuilder.new()

for seqNum in 1 .. 10
    sbMime.Clear()
    success = imapSrc.FetchSingleAsMimeSb(seqNum,false,sbMime)
    if (success == false)
        print imapSrc.lastErrorText() + "\n";
        exit
    end

    success = imapDest.AppendMimeWithFlagsSb("Inbox",sbMime,false,false,false,false)
    if (success == false)
        print imapDest.lastErrorText() + "\n";
        exit
    end

end

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