Why has Gmail blocked my messages?

Here at Gmail, we work very hard to fight spam. While in some cases we may classify a message as spam and deliver it to the spam folder, we also try to find ways to reduce the amount of spam being sent to Gmail in general. If we detect that a message has a strong likelihood of being spam, we’ll block the message from being sent to Gmail.

A message might be blocked if it contains suspicious-looking or spammy text or if the sending IP has had a history of sending unsolicited messages.

Is all of the mail I’m sending being blocked?

It’s likely that only a subset of the messages which have a strong likelihood of being spam are being blocked and not all of your messages. However, to help improve your deliverability, we recommend reviewing our Bulk Sender Guidelines.

If you’re forwarding mail to Gmail and your domain also forwards spam, we recommend reviewing our mail forwarding best practices.

Yep, previous owner was bad guy or carefree man, his IP was blacklisted and now your own this IP. There is no standart manual - need to write, need to cry, need tell true story and need to pray about release from blacklist. It's sad, but there no other way, besides to contact with spamlist owners and clear your IP.

Not necessary.
PTR record it's important, but SPF more important ;-)
