high volume email sending

I'm wondering if anyone here has worked on an app that involved
sending lots of emails (1000+ emails per hour) from inside the rails
app. Did you use sendmail, an smtp server or a specialized service?

We don't send lots of emails continuously, but we do have a daily
'fact of the day' which we send out to a fair number of subscribers,
via a cronjob that talks to sendmail.

Fredrick, Do you use the action_mailer feature of rails to send off
the emails or something?

yes.

I'd suggest considering a service such as authsmtp.com. If you're
generating lots of emails, it is hard work to stay off the blacklists
and keep your messages from being blocked as spam.

I use sendmail for some low-volume mail sending but would use authsmtp
or something similar if volume was higher.

Michael & Fred,

Thanks for your feedback. I think the way I'll do it is run sendmail
until it starts hitting 100 emails per hour and then switch out to
authsmtp.
