Well, https://support.google.com/mail/answer/81126?hl=en suggests using 
the same IP's, having reverse DNS records set up, and also use something 
like DKIM. I can see by DNS lookup that you don't have a DKIM TXT 
record. DKIM would be my recommendation, rather than telling people they 
can't use Gmail.
