notification emails blocked by spamhaus

BJohnson

Hello,

I'm not receiving alerts from my UTM because spamhaus.org is blocking the email.  I don't even know who that is; our email and spam services are provided by the same provider.  Is spamhaus a free service used by the UTM?

How do I ensure I receive these alerts? I've already whitelisted the UTM's static IPs with our service provider.

Thanks,

Brian

    It should provide you with a link to a site to check and see if your IP as any marks. I bet your ip is listed.

    If you go to your email logs I bet its failing a RBL check.

    Go to the link below and enter your ip address and it will tell you. If it is listed you will have to ask for you ip to be removed.

    As a moderator, Brian, I can see the IP from which each post was made.  Your IP is blacklisted on Spamhaus ZEN - I will guess that that's because you have a cable connection without a fixed IP.

    If you have a dynamic IP, your service provider will need to do something else to allow email from your IP.

    If you do have a fixed IP, you should ask Spamhaus to take you off their blacklist.

    Cheers - Bob

    Bob, thank you for checking this out.  You are correct regarding our connection, as I learned myself late yesterday.  We do have a dynamic IP that is part of a range which is reported to SpamHaus as automatically suspicious because it's for consumer-grade, dynamic connections.  All dynamically assigned IPs are supposed to be reported to SpamHaus.

    You should configure UTM to submit mail to a mail server using authenticated SMTP on port 587 or 465.    You can do this without changing your home connection, assuming that you have an email account that allows IMAP or POP connections.

    You are being blocked because you have UTM Notifications acting as a mail server instead of acting as a mail user.

    That's a better solution, Doug - I knew that!  I have several small clients that use an email account at Google as their smart host - port 587.  Thanks for backing me up - sometimes even a simple grounder slips by. [;)]

    Cheers - Bob

    Configuring the UTM to use SMTP on port 587 was the answer, but unfortunately there's still a problem.  I'm not receiving this notification:

    Email
    SNMP
    WARN-030 Primary internet uplink is down, switching to backup line

    I received a login notice after I disabled our primary internet service, so I know that the SMTP alerts are working.  Is it possible that the UTM doesn't know which uplink is primary because I'm using load balancing?

    Confirming DouglasFoster about UTM has to send emails as client if you dont own your domain. 

    1) Here in forum search for gmail less secure smtp. 

    2) Check in multipath rules and allow smtp to use both uplink intefaces
