(Ruby) Secure IMAP over TLS/SSL

To communicate with an IMAP server over TLS/SSL, simply set the Ssl and Port properties. The remainder of your code is the same as with non-SSL.

Note: This example requires Chilkat v11.0.0 or greater.

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

require 'chilkat'

success = false

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

imap = Chilkat::CkImap.new()

# To use a secure TLS/SSL connection, set the Ssl property and the port:
imap.put_Ssl(true)
# The typical port for IMAP SSL is 993
imap.put_Port(993)

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

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

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

# Get the message IDs of all the emails in the mailbox
fetchUids = true
messageSet = Chilkat::CkMessageSet.new()
success = imap.QueryMbx("ALL",fetchUids,messageSet)
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end

# Fetch the emails into a bundle object:
bundle = Chilkat::CkEmailBundle.new()
headersOnly = false
success = imap.FetchMsgSet(headersOnly,messageSet,bundle)
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end

# Loop over the bundle and display the FROM and SUBJECT of each.
email = Chilkat::CkEmail.new()
i = 0
numEmails = bundle.get_MessageCount()
while i < numEmails
    bundle.EmailAt(i,email)

    print email.ck_from() + "\n";
    print email.subject() + "\n";
    print "--" + "\n";
    i = i + 1
end

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