[SOLVED] 550-No Such User Here 550 Sender

Hi everyone
I have see the manual and nothing comes out of how to configure postfix or bind.

The problem is that I can not see mydomain.me.
I have also set up an email and when I try to send an email, it returns me: 550-No Such User Here 550 Sender.
I followed the https://www.howtoforge.com/tutorial...l-pureftpd-bind-postfix-doveot-and-ispconfig/ and i could not configure my domain.

Thank you in advance for all the help you can give me.

I have the following configuration:
File hostname on /etc

Code:

root@server1:/etc# cat hostname
server1

File 'hosts' on /etc:

Code:

root@server1:/etc# cat hosts
127.0.0.1       localhost
192.172.1.50    server1.domain.me server1
[...]

File 'resolv.conf' on /etc:

Code:

root@server1:/etc# cat resolv.conf
[...]
nameserver 192.172.1.50

File 'named.conf.options' on /etc/bind:

Code:

root@server1:/etc/bind# cat named.conf.options
options {
  directory "/var/cache/bind";

  // If there is a firewall between you and nameservers you want
  // to talk to, you may need to fix the firewall to allow multiple
  // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

  // If your ISP provided one or more IP addresses for stable
  // nameservers, you probably want to use them as forwarders.
  // Uncomment the following block, and insert the addresses replacing
  // the all-0's placeholder.

  // forwarders {
  //  0.0.0.0;
  // };

  //========================================================================
  // If BIND logs error messages about the root key being expired,
  // you will need to update your keys.  See https://www.isc.org/bind-keys
  //========================================================================

File dns for my domain on /etc/bind:

Hello Till, I love this panel, if it helps me to configure my server with my own dns and that my mails will run support them for a long time.

Thank you

 

Hi Till thanks for you reply:

I can already see my server from outside: in pri.domain.me I have the following and this work fine:

Code:

$TTL 10800
@ IN SOA server.domain.me.    postmaster.domain.me. (
    2017072306  ;serial
    21600    ;refresh after 6 hours

    86400   ;expire after 1 week
    86400 )    ;minimum TTL of 1 day

server        3600        IN        TXT            "v=spf1 mx a ~all"

The problem now I have it with my email account. If I send an email to my account, everything is fine, but if I send it to some other mail I receive: Diagnostic-Code: smtp; 550-Verification failed.

In my Master i have:

Code:

  -o syslog_name=postfix/submission
  -o smtpd_tls_security_level=encrypt
  -o smtpd_sasl_auth_enable=yes

What will be the problem and thank you very much for the help you can give me ...
One more thing that I forgot: If I send an email to my account in hotmail it arrives at unwanted mails, but if I send it to a personal email account it does not.

 

Hi Till, thanks you for you fast reply.

Yes, if I send an email to my hotmail account I get it, but if I send an email to my account [email protected] I get the message:
550-Verification failed.
This appears in the hotmail header:

I can connect via ssh from an external ip, I am using JuiceSSH.
And yes, I can receive my own emails.

 

I can not paste more than 10,000 characters:
https://prnt.sc/g0gq1f

 

Something strange I've seen is that when I dig the domain I get the following:

Code:

Thanks Till, it's very kind ...
This is very strange, if you like write to the mail with which I registered and give you access by ssh.
