    Hello 2 u all,
    I own my cpanel whm servers since over 3 years and had never problems after an update of the version - but now:

    OK, what is my problem:
    I own 2 Servers at different providers - I use the DNS from provider A to host the domains for both servers. That worked fine until friday.

    When I send mails from server A to GMX/WEB.DE/ other domains outside server A , everything works fine.
    When I do the same from server B I get the following error-message:
    Code:
    
    This message was created automatically by mail delivery software.
    
    
    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:
    
    
      username@web.de
    
        host mx-ha03.web.de [212.227.15.17]
    
        SMTP error from remote mail server after RCPT TO:<username@web.de>:
    
        550-Please turn on SMTP Authentication in your mail client.  (wss.ws-s.de)
    
        550-[144.76.203.39]:50040 is not permitted to relay through this server without
    
        550 authentication.
    
    That happends since the server was updated. I send using exim - SSL/TLS - port 465.
    That also happends, when cron or our shop is sending, not only the mailclient (Outlook, Thunderbird).

    If you need more information, please ask - I don't know how to solve that problem!

    Kind regards
    Thorsten

    OK, because it happened on both servers I took a look into the exim_mainlog.

    Thats what I found:

    Hello @tholler

    Do you happen to have a ticket open for this currently? I see that there are a couple tickets who's logs match these open right now. If you do have a ticket open can you please update this thread with the ticket ID?

    Thanks!

    Did you manage to get a resolution on this?
    I am experiencing the same problem now and the cPanel helpdesk is overwhelmed due to the v70 known issues

    I haven’t seen mess as cPanel v70, looking for alternative solution probably like Plesk as frankly having enough of v70 bugs
