Barracuda RBL blocking all IPs

Post by MauriceW »

Not sure if this is a problem of eFA or with Barracuda, but I thought I would ask here.

For years I have been using two RBLs in eFA's Postfix config under SMTP Client Restrictions: zen.spamhaus.org and b.barracudacentral.com

Today I noticed that I hadn't received any mail for a while and when testing with MXToolbox and GMail they both reported this:

554 5.7.1 Service unavailable; Client host [209.85.217.53] blocked using b.barracudacentral.com

The IP address is one from Google's GMail service, but the IP address that MXToolbox uses gave the same error.

As soon as I removed the Barracuda RBL from Postfix, mail started to arrive again.

Anyone else noticed this? I think it started yesterday evening somewhere after 18:00 CET.
