(Ruby) Delete All IMAP Email

Demonstrates two ways to delete all email in a mailbox on an IMAP server.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

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

imap = Chilkat::CkImap.new()

# Turn on session logging:
imap.put_KeepSessionLog(true)

# Connect to an IMAP server.
# Use TLS
imap.put_Ssl(true)
imap.put_Port(993)
success = imap.Connect("imap.someMailServer.com")
if (success != true)
    print imap.lastErrorText() + "\n";
    exit
end

# Login
success = imap.Login("myLogin","myPassword")
if (success != true)
    print imap.lastErrorText() + "\n";
    exit
end

# Select an IMAP mailbox
success = imap.SelectMailbox("Inbox.RubyMail")
if (success != true)
    print imap.lastErrorText() + "\n";
    exit
end

# Get the complete set of Uids for email in the selected mailbox.
# messageSet is a CkMessageSet
messageSet = imap.GetAllUids()
if (imap.get_LastMethodSuccess() != true)
    print imap.lastErrorText() + "\n";
    exit
end

# Set the Deleted flag for each message.
# (ExpungeAndClose must be called to finalize the delete.)
success = imap.SetFlags(messageSet,"Deleted",1)
if (success != true)
    print imap.lastErrorText() + "\n";
    exit
end

# Alternatively, the Deleted flag may be set for each UID
# individiually, but this is less efficient:

n = messageSet.get_Count()
for i in 0 .. n - 1
    success = imap.SetFlag(messageSet.GetId(i),messageSet.get_HasUids(),"Deleted",1)
    if (success != true)
        print imap.lastErrorText() + "\n";
        exit
    end

end

# Expunge and close the mailbox.
success = imap.ExpungeAndClose()
if (success != true)
    print imap.lastErrorText() + "\n";
    exit
end

# Display the session log.
print imap.sessionLog() + "\n";

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