Newsletter Confirmation Marked as Spam

[LazyD]

I have a newsletter signup setup on one of my sites and its a double opt-in so they have to click a link to confirm there signup.

However, it seems that they get marked as spam quiet a bit. Anyone have any general tips for not having a confirmation email marked as spam?

Does DomainKeys support php's mail() function?

take out all spammy words. Like 'money' or 'free' or 'viagra'

My favorite is when someone subscribes to the list, clicks the confirmation link in the double opt-in email, and then reports the welcome email as spam.
