    This morning, outbound e-mail to most domains was failing. GMAIL, AOL, LIVE, etc. They all failed with what appeared to be resolution issues.

    #554 5.4.4 SMTPSEND.DNS.NonExistentDomain; nonexistent domain ##

    As soon as we stopped using OpenDNS for external resolution, the issue went away. Did the system have any hiccups this morning? I checked around and didn't see anything posted about any issues.

    Thank you.

    Ok, have you figured out why? We've used OpenDNS successfully for years, and this started last week with us. I did same this morning, removed them from forwarders, and viola' it started to work again.

    I have experience the same issue. Outbound email bouces back with "Unrouteable address". If I switch from OpenmDNS as the primary DNS on our Instagate all mails works just fine. I was thinking there is a rout issue maybe due to the storm Beryl that just hit north Florida and Geogia this weekend?
    Thanks, ML

    We have no idea why. Like you, we have used OpenDNS for years without a single issue.

    ...and nobody raised a support ticket, right? :devil:

    If you expect any useful response from us users here in this user to user forum, you must be far more specific, e.g. examples of e-mail addresses (at least the part after the @) you're trying to send to.

    This is your only chance here if you don't find anything at http://system.opendns.com/

    I had the same issue on my servers. It seemed to happen throughout the weekend too in little spurts. How do we know if the issue has been resolved? I added google's DNS forwarders to my DNS server additionally to try and circumvent the issue.

    Happened to us as well. Nearly 4 days with gmail, yahoo, comcast mail not going through. I've dropped OPENDNS because of it as 4 days of lost mail is totally unacceptable.

    Same issue here with tons of clients using OpenDNS. I opened a ticket and will update this thread once I hear back.

    We opened a ticket as well. Has anyone heard anything on any of this yet? We changed our forwarders over to a google dns server 8.8.8.8 and got gmail.com and others cached for the time being. We then changed back to OpenDNS as we do not want to leave our networks unprotected. One of them is a school and it is critical that it be protected.

    The ones not having received an automatic ticket confirmation with a reference number may check their spam folders, also and especially via webmail interface. Big mail providers tend to treat mail from high volume domains as spam. Some mail providers dispose it in hidden spam folders, some even discard mail silently...

    I'm also experiencing this issue.

    I opened a ticket. In the meantime I changed my forwarders to use Google (8.8.8.8) which circumvents the filters that are in place.

    Add me to the list. I DID open a ticket. Gotta give them 72 hours to respond.

    Like others, I've been using them for YEARS without a problem. I'm cutting them some slack, but at some point I have to make a change. (one I don't want to)


    --EDIT--

    Brian posted below AND sent me an email saying all is well again. THANKS BRIAN!

    Since 8:47am Eastern Time this morning we've received the following for YMail and Gmail external recipients:

    #554 5.4.4 SMTPSEND.DNS.NonExistentDomain; nonexistent domain ##

    I just spent the last 4.5 hours troubleshooting our mail server, internal DNS servers and routing configurations and had our email server offline several times and now I finally find this issue!

    I'm going to try switching everything over to Google 8.8.8.8 and 8.8.4.4 and see if this resolves the problem.

    We have identified 1 server in Ashburn that was experiencing abnormal behaviors on some MX lookups. We have pulled that server and have our teams looking into what caused this behavior. I have confirmed with shamonkie that MX records are resolving properly for him at this time and expect they should be for everyone else who was affected.

    This was not something impacting all OpenDNS users or all servers so most users will have seen no effect what so ever. If you have any questions, please feel free to reach out to me at the information above.

    Just installed OPENDNS today and have been unable to send email. My ISP is roadrunner.com in Lancaster, CA. Everything else seems to work OK.
    Don't know what addition info you need, but at this point I'm ready to pul the plug on OPENDNS.

    This is a user to user forum. Better open a support ticket.
