Postfix is not sending or receiving mails

Hello

I am very new to linux servers and ISP / Dovecot / Postfix

So I got my server up and running with everything working for now, besides my mails. Postfix is configured as follows:

Code:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version


# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings

I am able to log in with Mailbird to get access to the account. Roundcube is also working. But sending is not giving me any error but do not send mails and receiving is giving me

Code:

Is there any way you can help me?

 

Thanks for the fast reply.

At least this fixed something, but now I am getting the following issue:

Code:

This is the mail system at host v22019078654392401.mail.nushara.com.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The mail system

<[email protected]>: host gmail-smtp-in.l.google.com[2a00:1450:400c:c08::1b]
said: 550-5.7.1 [2a03:4000:37:4ad:640a:8bff:fe7f:e663] Our system has
detected that 550-5.7.1 this message does not meet IPv6 sending guidelines
regarding PTR 550-5.7.1 records and authentication. Please review 550-5.7.1
https://support.google.com/mail/?p=IPv6AuthError for more information 550
5.7.1 . l24si56014wmg.136 - gsmtp (in reply to end of DATA command)

Also the "554 5.7.1 <[email protected]>: Relay access denied" issue is still present

 

Ok so I've checked my DNS records in ISP and found that there is no PTR record. But What do I have to put into the two inputs?
Putting in my IPv6 is not working. And the onlything i found on the net are some "zones" but this still does not give me a clue what to do here.

Would be great if you could explain this to me, since I am not that much into all this domain / networking stuff.

Thank you in advance!

 

Ok so since I can not have an impact on this, I've changed the inet_protocols = ipv4 and restarted.
Now the mail got into my spam but thats a gmail issue i think (already contacted barracuda or some sort of service)

So now I need to figure out how to solve the receiving issue. Any idea on that?

 

Ok so when I try to send a mail to the address I get an error from google:

Code:

554 5.7.1 <[email protected]>: Relay access denied

with a file attached:

Code:

Reporting-MTA: dns; googlemail.com
Received-From-MTA: dns; [email protected]

Last-Attempt-Date: Thu, 12 Sep 2019 07:37:25 -0700 (PDT)

The IP shown (85.114.133.20) is not the same as the ip of my server. But I dont know, where this is coming from (maybe google?) this is also not my local ip of my ISP i am connected to atm.

 

Ok so it looks like the mx record is wrong in some way..

MX Records
10 mail.nushara.com 85.114.133.20

Right now i have the following MX Records:
MX mail mail.nushara.com 10 60
MX nushara.com. nushara.com. 10 3600

So I change this to nushara.com to see if the ip is valid after the dns refresh

I will report back if there is any progress.

Thank you very much for your help!

 

But thats already pointing to the right IP? To what do I need to change this?

 

right now it is pointing to:

A mail 91.132.145.24 0 3600

So I dont know, there this other IP is coming from

 

Well I dont know but this looks strange .. i have this record on my ISPConfig.

 

Ok, now that I have added them to the hoster it seems to work. I can now receive mails too

But why is the service freaking out about the name server so much? You also mentioned this might be an issue right? Do I have to change them too?
