From the logs I picked the email address and tested it. Trying to send any email to said address fails with 554 5.7.1 Relay Access Denied meaning mail is rejected. The remote server is not setup correctly.

Also you can use the steps here to debug your email configurations. Remember email debugger (https://SERVER:8090/emailPremium/EmailDebugger) is a paid option but solves most issues.

yes, thanks. i did not setup my dns records. which i have done now.

But i sent emails to a “yahoo” mail and “hotmail” it did not deliver. But when i sent to mail-tester.com, i got a mailing score of 10/10.

this is the error message i got for the yahoo mail…

    Unfortunately, messages from [191.101.233.155] weren't sent. Please contact
    your Internet service provider since part of their network is on our block
    list (S3140). You can also refer your provider to
    http://mail.live.com/mail/troubleshooting.aspx#errors.
    [VI1EUR05FT054.eop-eur05.prod.protection.outlook.com] (in reply to MAIL
    FROM command)

and this for the hotmail.

From your error report it shows Yahoo error code 553. According to them this either indicates:

  1. Server is blocked by reputable threat intelligence company or on a blackilist block Yahoo consumes in their system. Your spamhaus result for Hostinger server you are on.

  2. Possibly your email failed authentication checks against your sending domain’s DMARC or DKIM policy. setup DKIM DNS records for your domain DKIM signatures allow Yahoo to associate email with the sender and verify that the content of the email has not been changed during transmission.

Also, publish valid SPF records, which allow a sender to specify the list of IPs which are allowed to send mail for that domain.

As for Hotmail since part of their network is on our block list (S3140) just contact Hostinger or your hosting provider and inquire if your server ip address is blocked by Hotmail/Outlook. They will do necessary measures to sort it out.

show me the result of checktls?

please could you explain better? i do not understand
