just a quick hack, but useful…
This blog shows how to send mail via gmail.
http://blog.pomozov.info/posts/how-to-send-actionmailer-mails-to-gmailcom.html
It does it by replacing some methods in Net::SMTP with versions that
do the right TLS thing (this likely only works on linux, which is fine
for me).
The annoying thing is that with this lib, you can no longer send to a
“normal” smtp server. So I did this…basically just take the old
path if not a gmail smtp server, take the new path if gmail.
require “openssl”
require “net/smtp”

Net::SMTP.class_eval do

def do_start(helodomain, user, secret, authtype)

raise IOError, ‘SMTP session already started’ if @started

@socket = InternetMessageIO.old_open(@address, @port,
@open_timeout, @read_timeout,
@debug_output)
check_response(critical { recv_response() })
begin
if @esmtp
ehlo helodomain
else
helo helodomain
end
rescue ProtocolError
if @esmtp
@esmtp = false
@error_occured = false

authenticate user, secret, authtype if user
@started = true

@socket.close if not @started and @socket and not @socket.closed?
