Sending out lots of mails from Rails - what are people using these days?

In other apps i've used ar_mailer to queue up mails and ar_sendmail to take them out of the queue in a seperate process. I've not been massively happy with this setup: the ar_sendmail process seems to开发者_Go百科 silently die fairly often, and in the default configuration mails are deleted out of the emails table when sent: i'd rather keep them for future reference and just mark them has having been sent.

I'm adding emailing into another project now (which uses rails 2.3.8) and am wondering what other solutions have people used in rails for bulk emailing?

Grateful for any advice - max

I think the prevailing opinion is to use a bulk e-mail service like MailChimp (http://mailchimp.com) or Amazon Simple Email Service (http://aws.amazon.com/ses)
