To resolve the exact security certificate name mismatch obstacle, this morning I followed the recommended steps in How do I fix a Mailbox server SSL connection? followed, but now whenever I am about to send an email from that client (in this case the user is Windows Mail) I get the following error.

The rejected email address was [email protected]. The theme “This Test. ‘, Account:’ mail.domain.com ‘, Server: ‘mail.domain.Protocol:com ‘, SMTP, server response:’ 554 5.7.1 ? Relay access denied ‘, Port: 25, Security (SSL): No, Server error: 554, error number: 0x800CCC79

Edit: I can still receive emails from your account and send emails to make sure you have other accounts on the same domain name. I just don’t send emails to make sure you are a recipient outside of our domain.

By the way, an employer wants to be able to send clients emails (Thunderbird or Outlook) both inside and outside of our public network.

I put the suffix on air on the mail server in my VPS Linode. The intention is often to create an account to create [email protected] for each user account on the server. These accounts should preferably be able to send and receive email.

Currently, I can send emails if they are stored on the server. I, Maybe I can do it through the national teletet or the mongrel.

I can also successfully receive external emails, but only from a remote computer that supports telnet. For example, if I use telnet mail.mydomain.org 25 on my entire computer from home, I can compose and send emails that go to my owner’s maildir account on the server. However, when I send an email from my home computer to [email protected] , it is not. stay. I am getting the following lines in a simple systemctl -l status postfix output, which I have currently masked some possible urls / emails for, but that was for good emails from my [email is being protected] ) user user on my vps-linode (here [secure email] ).

Despite a valid reverse DNS server and MX record, as verified by countless online workstation tools and the success of Telnet at mydomain.org, the record in the second sentence specifies an address from [email protected] can be X). Where does this address come from? I understand why my Postfix SMTP hosting server is rejecting incoming mail because liXXXX-XXX.membsers.linode.com has no relation to the $ mydestination records. But location, why and how changed from [email protected] to [secure email address] ?
