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)
I tried sending email from my mailserver to my email address on other domain name by google app gmail server and email on rediffmail, both work!
Yahoo, hotmail, gmail don't accept my emails from my mail server, Rediffmail does accept my email.
Right now I am receiving mail on my self-managed server and sending email via gmail's "Send email as" feature so I can send to everyone.
Is any special class of IP or service is required to have my own mailserver? I have a half working email server which receives 100% mails but sends only to few email addresses. Any help?
