Question RBL list problem inbox email

Plesk version and microupdate number

Plesk Obsidian 18.0.69

Hi, I have several servers with Plesk on Linux, and on all of them I use RBL spam lists for incoming mail, such as Barracuda and Spamhaus.


For the past few days, many incoming emails are being blocked that weren't being blocked before. On the Spamhaus website, they don’t appear as blacklisted.


Do you know if there’s a problem with the RBLs or if I might be doing something wrong?

Make sure that you aren't using public resolvers with SpamHaus:
