      Hello,

      1. Check whether the configuration of the roundcube is correct? 135roundcubemail.com to your domain name
        Modify this file:
        /www/wwwroot/135roundcubemail.com/config/config.inc.php
        Add the following:
        $config['enable_installer'] = true;
        Then the browser accesses: http://135roundcubemail.com/installer/?_step=2
        Finally, test the IMAP settings
      2. Can't send to yahoo. Is there any error in returning? With, you can send multiple emails at one time.
      3. Unable to send dkim information header, try to change the permission of the file below
        chmod 644 /www/server/dkim/xx.com/default.private
        systemctl restart rspamd

        I get this error when i send email zohomail.com to my domain mailbox "Recipient address rejected: User unknown in local recipient table"
        why if I send email to gmail it enters spam and it doesn't enter hotmail.

        Please can I send you my control panel login details so that you help me and configure postfix and the roundcube correctly?

          aaPanel_Kern

          I did the testing and it showed 4.7/10
          the things I noticed on the mail header are:

          1) * Received: from bk.com (unknown [8..*.7])
          2) * 1.3 RDNS_NONE Delivered to internal network by a host with no rDNS
          3) * -1.274 RDNS_NONE Delivered to internal network by a host with no rDNS
          This may indicate you do not have a rDNS configured for your hostname or the rDNS does not match your sending IP

          4) Please how do I configure my server rDNS and how to make my mail have dkim pass?
          I configured the dkim record in my server, but it does mark pass on my mail headers.

          Please how do I solve these above issues in my server to make my mail have good reputation?
          and what are the things I need to uncooment or add in the postfix cinfig file?

          Thank you.

            Hello, please consult the server provider or network provider for rDNS resolution of IP.
            The transmission of the dkim indicates that the configuration is normal

              aaPanel_Kern
              the server rDNS is showing on my vps panel.
              so how will I configure it on the aapanel to resolve with my mail server?

                mac_dolar
                Refer to this article. You need the help of a server provider or network provider
                https://en.wikipedia.org/wiki/Reverse_DNS_lookup

                  why I can send email from the webmail, but I can't send mail using SMTP, its shows this error below

                    Hello, please try to reapply for SSLs at the mail server. At the same time, check the postfix configuration, which can be viewed in the server status
                    "mail.135mailtest.com" is replaced with your domain name
                    Put:
                    smtpd_tls_chain_files=/etc/ssl/private/ssl-cert-snakeoil.key,/etc/ssl/certs/ssl-cert-snakeoil.pem
                    Change to:
                    smtpd_tls_chain_files = /www/server/panel/plugin/mail_sys/cert/135mailtest.com/privkey.pem,/www/server/panel/plugin/mail_sys/cert/135mailtest.com/fullchain.pem
                    Note to replace 135mailtest.com with your domain name.
                    Also check /www/server/panel/plugin/mail_sys/cert/135mailtest.com/ for privkey.pem and fullchain.pem files
                    You can use this command to check whether the correct SSL is configured
                    openssl s_client -connect mail.135mailtest.com:587 -starttls smtp
                    or
                    openssl s_client -connect mail.135mailtest.com:465 -starttls smtp

                      aaPanel_Kern
                      please where can I locate this file below you said I should modify?
                      smtpd_tls_chain_files=/etc/ssl/private/ssl-cert-snakeoil.key,/etc/ssl/certs/ssl-cert-snakeoil.pem

                      I have tried to configure the mailserver many times, but it keeps on not working properly.
                      Please wouldn't it be better I give you me aapanel login details so that you help me and configure the postfix mailserver?

                      thank you.

                        Hi, can you give us your aapanel information? The server makes a snapshot backup first, if possible, please send it to kern@aapanel.com.
                        It is recommended to fill in the following

                        aapanel login link address and account password:

                        No post link will not be able to know which user's information is
