How to send validation email without going into the spam folder?

I have this PHP server that sends verification emails to the users.

Whenever the system sends a verify verifcation to a user, GMAIL marks it as spam. What do I need to do to make it stop? It is hard for me to explain to the clients what to do and it is not right.

Answer 1

Its not PHP, its the SMTP server you're sending from.

Even until recently, sugarsync emails still get spam filtered by gmail.

Answer 2

You should ensure that the subject of the email or body doesn't include any irrelevant text that could be interpreted as spam?
