IP blacklisted

Ignacio Roig 4 months ago

Hi,

The following IP are blocklisted by you:

104.245.209.235

With the following message:

smtp;550 Sophos Anti Spam Engine has blocked this Email because the sender IP Address is blacklisted.

I am trying to delist them using the following link, but the captcha is not working:

www.sophos.com/.../ip-address-lookup

Hello there, Labs have confirmed that they aren’t blocking the IP/Domain; the block is at the customer product configuration. Here’s a reference to the UTM/Firewall/SFOS docs that highlight this fact…

Hi Erick,

We are experiencing this issue with several more IPs. Could I provide you with the full list so you can assist me?

Here's the information for a recent example with this specific IP:

From: Machinio Lisa lisa@machinio.com
Recipient: marianne@furrow.com
Response: smtp;550 Sophos Anti-Spam Engine has blocked this email because the sender IP address is blacklisted.

As I mentioned we are an ESP and we have a lot of IPs listed by you, I'll give you one example of them but this is not the only domain or IP seeing this issue.

Full log and .eml sample attached.

Affected domain of the example: bve.vc

Hello,

The .eml file you shared seems incorrect; please share a new one.

Also, it seems the blocks are happening at the configuration level (so the users are blocking the emails) rather than Sophos blocking your IPs, but Labs will be able to confirm.
