Issue Email doesn't arrive

[jonny_alex]

Dear pleskians,

I just received this error message, that my message was undeliverable to the adress i tried to reach..
Therefor i'd like to ask you Pro's if you have an idea why this error occurs?

The following message to <[email protected]> was undeliverable.

The reason for the problem:

5.1.0 - Unknown address error 550-'5.4.1 Recipient address rejected: Access denied. AS(201806281) [HE1EUR01FT029.eop-EUR01.prod.protection.outlook.com]'

Hi jonny_alex,

I see here two error codes: 5.1.0 and 5.4.1, I also see the "outlook.com" domain. I have found two documents from Microsoft about these errors:
- Fix email delivery issues for error code 550 5.1.0 in Exchange Online
- Fix email delivery issues for error code 550 5.4.1 in Exchange Online


I hope it can help you.

Since i'm not very aware of the settings i would have to do caused by inexperience, can i check somewhere if my settings are enough?

And is there a guide or assistance i can use to help me do the right settings?

I don't have any knowledge of the server or domain setups with DNS or anything i would have to do, and i don't want to mess it up..

I can suggest starting diagnosis with online tools like MX Lookup Tool - Check your DNS MX Records online - MxToolbox for your (sender) domain and asking the recipient to check their mail configuration that they are not blocking your domain.

SMTP Problem getting IP Address for mx.nail-barbara.ch SMTP Failed To Connect

Reverse DNS does not match SMTP Banner

This is the result of the check up.. What are the things to do now?

I have checked MX-record for your domain and see two records: "mail.yourdoma.in" and "mx.yourdoma.in". After that, I have checked A-record for each of these domains and found that "mx.yourdoma.in" does not exist. I think that can be a problem.

In my opinion, there are two possible ways to solve this:
- create A-record for "mx.yourdoma.in" and point it to your main server
- remove MX-record for "mx.yourdoma.in" and continue use "mail.yourdoma.in".
