simple mail with Ruby

Peter Bailey

1/15/2008 7:54:00 PM

Hi,
I just want Ruby to enable me to send simple e-mails, sometimes with an
attachment, if possible. Here's all I want:

To: pbailey@bna.com (that's me, as a test)
From: my account, whatever
Message: Some test text. More test text. And so on.
Attach: c:\simplestuff.pdf

The e-mail server here at my company is Lotus Notes. I've used it for
years as an SMTP server.

Thanks,
Peter

Wow! I need to look closely at this. This looks incredibly complicated
to me. How come you literally had to go in and create your own class?
Isn't there anything already available?

I'll dive in. Thanks a lot,
Peter

sure.

msg = "To: %s\nFrom: %s\nSubject: %s\n\n%s" % [@to, @from,
@subject, @message]
Net::SMTP.start("localhost"){|smtp| smtp.send_message msg, @to,
@from }

you'll need to encode you attachments by hand though. the class i
posted is just a wrapper on doing the above by hand each time.
mailfactory is really nice for building the actual email body too.
as far as built in is concerned though - net/smtp is as high level as
it gets.

regards.

Install actionmailer gem and every task with email will be easy. :D
Examples are in web.
