The mail server is listed in the blacklist. How to unblock it quickly?

Self built mail server , Listed as spam ,IP The address is blacklisted , This was a common thing many years ago , When I first solved this problem , still 2003 year , At that time, it was built by a customer Exchange Server It is caused by not doing reverse parsing .

Without inverse solution , At the time , If the email is only sent in China , That won't be a big problem —— Domestic mail service providers , At that time, reverse authentication was not strictly implemented .

And my clients , But it's a foreign trade company , So the mail server was established in a few days , I found that most emails can't be sent out , Send it to Sina 、 Tencent email , It will also be considered spam , Lying in each other's dustbin , Will not be read at all .

The irony is , Although I know the problem , But Telecom does not have this business process , It's not easy to explain the principle and necessity of inverse solution to the account manager , But I can't place a work order , You can't go to the main business hall .

I found the Engineer in the telecom room , He said it was easy to do , But how can I do it without a work order ？ therefore , I wrote an application by hand , Let the customer stamp , Send to the telecommunication room , The engineer asked the leader to sign again …… A toss down , Half a month passed , With the inverse solution , To Spamhaus Application for submission , Write an English email ,3-4 Days later ,IP It was unsealed , Then resume sending and receiving emails .

later , With the popularity of mail servers , Reverse solution has also become common sense , Of course, SPF Records, etc , Nowadays , Mail server IP Be on the garbage list , It is mostly caused by viruses 、 Caused by malicious programs , There was an example a few days ago .

In fact, the customer has been prompted , download 、 System patch installed , The problem with the mail server has been fixed , And already in Spamhaus The application was submitted on the website , But there was no reply , Nor has it been unsealed IP.

This is obviously not reasonable , therefore , Let the customer send the link of the event directly to me , I didn't know the problem until I opened it , Maybe the customer's English level is too poor , Maybe he wrote too casually , All in all , If I were Spamhaus Staff of , I won't help him unpack easily .

You can see from the above picture that , The customer just wrote one sentence ：“please remove my ip”. So here comes the question ：1、 Has the server problem been solved ？; Yours IP How much is? ？ And the tone is blunt , It sounds like a tough order , It's not pleasant to accept .

Confirm with the customer that the server problem has been solved , I wrote a new paragraph of application , In fact, it is also very simple , Explain the situation ：“We have already fixed the problem a few days ago, please help us to remove the IP:222.92.XX.XX, Thanks a lot.”—— We fixed the problem many days ago , Please help us remove IP, And thank you .

Due to the time difference , The other party cannot reply soon , I guess I'll always wait 1-2 God , It is gratifying that , only 4 After one hour , I received the reply from the other party —— I should have seen my application as soon as I went to work , Then removed IP.

In fact, the matter is so simple , There's no technical content , Problems that have plagued customers for many days , It's solved in one sentence , So , A lot of times , It's not a technical problem , It's communication skills —— At least make it clear .
