Hi fellas, I need to get more info of a blacklisted IP. This is a new IP provided and I don't know what happened but appears this error in more than one firewall protected deastinations, so we have to fix this and email sent some hours ago still wasn't replied.
This is the error we get:
--== Cut Here ==--
Mail delivery failed: returning message to sender
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
protected.address*@accenture.com SMTP error from remote mail server after RCPT TO:protected.address*@accenture.com: host mail.global.frontbridge.com [213.199.180.150]: 550 5.7.1 Service unavailable; Client host [128.128.128.128] blocked using Blocklist 1, mail from IP banned; To request removal from this list please forward this message to delist@messaging.microsoft.com and include your ip address 128.128.128.128
--== Cut Here ==--
Alternatively, I've been searching for public blacklist checks and nothing appeared.
It looks like an error to me, but I need to know if exists any way to check how and when was this error (or SPAM abuse) generated and any other ways to fix it, if possible.
Any help will be welcomed !!!
Many thanks
