Sendmail, rails and spam

We’re having a terrible problem with sending email using sendmail and

We believe we have everything set up correctly. (I’ve changed the
domain name below because this is so embarrassing ). Our mail config
looks like

ActionMailer::Base.delivery_method = :sendmail
ActionMailer::Base.sendmail_settings = {
:location => ‘/usr/sbin/sendmail’,
:arguments => ‘-i -t -f [email protected]

our notifications look like

@from       = "oursite <[email protected]>"
headers         "Reply-to" => "[email protected]"

and we have an SPF record that resolves back to your one and only
server. EMails are making it into gmail, fine, no problem, but are
getting flagged as spam in Yahoo and are not even making it into
Hotmail (which is crazy because my old hotmail account has around
2000+ new messages in the inbox 99% of which are spam, and 11 in the
spam folder, 2 of which are legit).

This may be off topic but I’m just stumped, and I’m not smart enough
to work this out on my own. Does anyone have any suggestions on how to
get this working or an alternative method (we’re using Slicehost for
hosting if that make a difference).

Thanks in advance

I’m certainly no expert in this regard, but one (of many) gotcha’s are
reverse dns. Be sure to have your hosting provider set it up.

There’s a link I tried to find that lists the top ten reasons why this
can happen - that was one I didn’t know about. Google may turn it up.


Thanks Jodi, we’ll give this a try and see if it works
