Last friday night Bell NOC staff informed us that based on our reports they had found an issue with their DNS resolvers and would be committing a patch overnight friday. This appeared to rectify things until this morning we began receiving reports once again that email originating on the Bell Canada, Bellnexxia network is sporadically being delivered to the domain name’s A record instead of the designated MX record.
We have been working closely with Bell NOC staff on this issue which is currently priority one here. Bell staff have been very responsive and forthcoming, we are happy to report. It’s just that something weird is going on and we’re all trying to figure out what that is.
We are only receiving reports of this behavior from users within the Bell Canada/Bellnexxia network at this time.
If this is having an impact on you, please forward as much information as you can to our support staff at email@example.com. We need mail headers, what local DNS resolvers you are configured to use, and if you can replicate the issue from a command line and email us the results we will be very much obliged.
Thanks to all for their co-operation and patience in this matter.
