I work with a small regional ISP and our main domain has been getting
blocked by Gmail since February 6. Our logs indicate we haven't sent a
huge volume of data to Google or anything. Our reputation has been
really good in Postmaster Tools until the 6th when it went straight to
the bottom. We never saw any indication of compromised accounts or
anything.
We've been watching and waiting for it to clear up, but it hasn't. Other
domains can send through our system, but internetpro.net cannot. I was
hoping someone here might be from Google and could take a look. Even
the reports under Postmaster Tools look wrong as we have a 100% delivery
error rate, but all of the "Error Types" show 0.0%.
Here is a sample of what we're seeing:
---BEGIN
74.125.138.26 failed after I sent the message.
Remote host said: 550-5.7.1 [74.252.14.252 7] Gmail has detected
that this message is likely
550-5.7.1 unsolicited mail. To reduce the amount of spam sent to Gmail, this
550-5.7.1 message has been blocked. For more information, go to
550 5.7.1 https://support.google.com/mail/?p=UnsolicitedMessageError
o20-20020a81de54000000b006041f08d2dfsi1515206ywl.160 - gsmt
---END
This seems to indicate that it is content filtering, but no matter what
content the messages hold, we get the same.
Even if someone wanted to reach out off list, that would be great.
