I am new to mail servers.
my domain name is revant.me (you can know ip/smtp/rdns ptr etc. now)
I bought static IP from MTNL Mumbai and they also changed Reverse DNS for me recently (Week ago)
I have recently configured mailserver (postfix/dovecot/roundcube), email domain and mailbox with IPConfig3 on my Server
My server is running debian amd64 stable, the LAMP is ON since May 2013.
With my recently configured mail server I can receive emails.
When I send email from my server to gmail, hotmail, facebook, yahoo I get "Undelivered Mail Returned to Sender" or similar email message:
Example Gmail error: 550-5.7.1 [my static IP] The IP you're using to send mail is not authorized to 550-5.7.1 send email directly to our servers. Please use the SMTP relay at your service provider instead. Learn more at 550 5.7.1 http://support.google.com/mail/bin/answer.py?answer=10336 vb2si7620646pbc.217
- gsmtp (in reply to end of DATA command)
From the support link:
"In order to prevent spam, Gmail refuses mail from IP addresses that are not authorized to send mail. The determination of whether or not an IP address is authorized to send mail is made by the ISP that provides you with the IP address. This list typically contains consumer IP ranges offered for dialup, DSL, or other broadband access."
The IP is listed in a few DNSBL.

You can try requesting each one of those lists to remove your IP, especially Spamhaus.
