Gmail.com detect mail as spam, but the server is not on any BlackList
- by Tomer W
I have an issue with Google. (GMail to be exact)
About 1 month ago, we had a security breach, and mail was relayed through our servers.
we got listed in almost ALL Black-Lists :(
we fixed the problem, and requested removal from Black-lists, which was granted easily.
currently (over 3 weeks), we are not sending any spam anymore.
furthermore, we got clear from all the Black-lists (MxToolBox Black-List Search Result)
But, GMail still refuse to get Anything from the server, stating '550 Spam'.
Following, Telnet attempt to send to gmail:
220 mx.google.com ESMTP g47si45436208eep.123
helo megatec.co.il
250 mx.google.com at your service
mail from: <[email protected]>
250 2.1.0 OK g47si45436208eep.123

i tried filling the form @ Gmail - Report Delivery Problem
i also tried reaching Google by phone, but the message was to go to the Link mentioned above.
I Checked ReverseDNS and is ok...
We dont have TLS, but that shouldn't be a problem, shouldn't it?
Note: we are not a Bulk sender.
Anyone has an idea? what can be blocking our IP?
Anyone know whom can be contacted in order to resolve this BL listing?
