Smtp_tls 1.0.3 Released

smtp_tls version 1.0.3 has been released!

Provides SMTP STARTTLS support for Ruby 1.8.6 (built-in for 1.8.7+).
Simply
require ‘smtp_tls’ and use the Net::SMTP#enable_starttls method to talk
to
servers that use STARTTLS.

require ‘net/smtp’
begin
require ‘smtp_tls’
rescue LoadError
end

smtp = Net::SMTP.new address, port
smtp.enable_starttls
smtp.start Socket.gethostname, user, password, authentication do
|server|
server.send_message message, from, to
end

You can also test your SMTP connection settings using mail_smtp_tls:

$ date | ruby -Ilib bin/mail_smtp_tls smtp.example.com submission
“your username” “your password” plain
[email protected] [email protected]
Using SMTP_TLS 1.0.3
-> “220 smtp.example.com ESMTP XXX\r\n”
<- “EHLO you.example.com\r\n”
-> “250-smtp.example.com at your service, [192.0.2.1]\r\n”
-> “250-SIZE 35651584\r\n”
-> “250-8BITMIME\r\n”
-> “250-STARTTLS\r\n”
-> “250-ENHANCEDSTATUSCODES\r\n”
-> “250 PIPELINING\r\n”
<- “STARTTLS\r\n”
-> “220 2.0.0 Ready to start TLS\r\n”
TLS connection started
<- “EHLO you.example.com\r\n”
-> “250-smtp.example.com at your service, [192.0.2.1]\r\n”
-> “250-SIZE 35651584\r\n”
-> “250-8BITMIME\r\n”
-> “250-AUTH LOGIN PLAIN\r\n”
-> “250-ENHANCEDSTATUSCODES\r\n”
-> “250 PIPELINING\r\n”
<- “AUTH PLAIN BASE64_STUFF_HERE\r\n”
-> “235 2.7.0 Accepted\r\n”
<- “MAIL FROM:[email protected]\r\n”
-> “250 2.1.0 OK XXX\r\n”
<- “RCPT TO:[email protected]\r\n”
-> “250 2.1.5 OK XXX\r\n”
<- “DATA\r\n”
-> “354 Go ahead XXX\r\n”
writing message from String
wrote 91 bytes
-> “250 2.0.0 OK 1247028988 XXX\r\n”
<- “QUIT\r\n”
-> “221 2.0.0 closing connection XXX\r\n”

This will connect to smtp.example.com using the submission port (port
587)
with a username and password of “your username” and “your password” and
authenticate using plain-text auth (the submission port always uses SSL)
then
send the current date to [email protected] from [email protected]

Debug output from the connection will be printed on stderr.
