RBL working too well

mkleine

Greetings, 

Yesterday morning I upgraded to firmware version 9.705-7. This morning at about 6:00 am the RBL feature has started rejecting well-known hosts. Shown here are oktax.state.ok and pharmacy.cvs.com. 

Checking pharmacy.cvs.com with www.anti-abuse.org I see that it's all green.

I have turned off the RBL checks in the SMTP Antispam page and those email addresses are now going through the mail server.
However, so are any 'bad-guy' sites that actually test as RBL failures. So, this is a workaround, not a fix.

Thoughts?

    I am experiencing the same issue and installed version 9.707-5 on model SG430. This happens with zen.spamhaus and cbl.abuseat; we also had to disable the RBL in order receive emails that were not registered in those lists.

    We are facing the same issue on two boxes on which we have installed version 9.707-5 two weeks ago. Yesterday evening the SMTP Proxy on both devices started to block several e-mail from different domains, which cannot be all at the same time on a blacklist. This happens with cbl.abuseat.org.

    Does anybody have a fix for this issue?

    Hallo Alexander and welcome to the UTM Community!

    Did you try my suggestion above?  Also, a reboot?

    Cheers - Bob

    Yes, we tried at first to restart the STMP-Service, which did not fix the issue and afterwards we rebooted the devices. Unfortunately this did no help also.We have disabled the RBL-Check for now and opened a ticket.

    Since today we have the exact same Problem.

    We discovered this toda at 10 am around.

    Rebooting does not fix the Problem.

    The Mail Adresses and most of the IP's where blocked from one RBL, but if u navigate to the RBL Website and check them, they are Rosponding, everithing is OK....

    We have a Critical Case Opend at Sophos, if we get a Solution i will provide it here.

    Hope someone of u is a bit faster ^^
