Recently, a new problem has surfaced in SBCglobal email service, which is making users go mad. The problem is ‘error 521’, and it is related to the emails getting blocked when the IP address is banned due to spam content or objectionable behavior by email users. Today, we will be fixing this particular problem, so if you too are facing this error, then follow the instructions that are given below.
It is completely fine to experience certain errors in an email service as long as you know how to resolve the problem. If you are seeing error code 521 while using SBCglobal email, then I would like to ask you if you know how this error has occurred in the first place. Let me tell why you are facing this error.
Error code 521 will disable email server from sending emails. You will get a non-delivery report, which will include this code. Moreover, you will also see that a particular mailing system has blocked.
Now coming to the reason as to why it is blocked, then it is due to the objectionable behavior reported by the email server. You must have sent some emails intentionally or unintentionally that are deemed as spam. Not just spamming, but your mailing system has also been banned due to network related abuse. When such behavior is seen by SBCglobal system or by other authorized bodies that monitor network activity, then they block such email servers. If you aren’t able to send emails to any of your contacts, then you will have to check whether your IP address hasn’t bene misidentified as spam.
Maybe your IP address has been added to the list of spam IP list or banned due to objectionable behavior. If you are dealing with this problem, then there is nothing to worry about, as you can follow below-mentioned steps to fix this problem.
- Go to 3rd-party source websites in which you can easily find as to whether your IP address is blocked or not. Once you are able to find it out, then it will be easier for you to move onto getting the solution for the problem. If your IP address is given on the list of banned IP address list, then you will have to follow the instructions to request for removal of your IP.
- You can go to the official site of the company to remove IP address from the list of blacklisted websites. This is the link to that website: SBC Global
One important thing to keep in mind is that the process you wish to perform to a request for removal of IP needs to be completed by the system admins and not by individual experts. You need to add certain information in order to finish the process. That information is only available with the SBCGlobal administrators.
