My site's legit e-mails being blocked by school spam filters

[apinomus]

I have developed a site with a user-login based system that requires the user to register with their e-mail address as their username and allows them to use whatever password they want. To keep people from making bogus accounts, I of course send them a confirmation e-mail address with a link inside to another page on my site where it will activate their account if they visit it.

The problem is, the target users are school teachers, and the activation e-mails being sent by my site via php mail() are being flagged as SPAM by their mail filters and the teachers are not receiving any email from my site.

Is there something I can do to keep my legit emails from being flagged as spam? For reference, not even Hotmail flags the email as spam, but I assume these schools have custom spam rules. Here is an edited version of the activation e-mail sent when a user registers an account:

Subject: Reading First - Account Activation ([their e-mailaddress])
Body:

Contact the email admins to find out why your emails are being flagged as spam.

Is your smtp server on any blacklists?

The email origin domain is a University, so I doubt it 🙂
