After upgrade to V70 I can't send mail outside my server

Thorsten H.
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: 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:: 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: 2018-05-19 09:02:33 cwd=/var/spool/exim 3 args: /usr/sbin/exim -Mc 1fJvsv-0000ms-8s 2018-05-19 09:02:33 1fJvsv-0000mt-92 Sender identification U=mailnull D=-system- S=mailnull 2018-05-19 09:02:33 1fJvsv-0000ms-8s Sender identification U=mailnull D=-system- S=mailnull 2018-05-19 09:02:33 1fJvsv-0000mt-92 => info R=virtual_user T=dovecot_virtual_delivery C="250 2.0.0 CLShGgnM/1qNCwAAIzJ5jg Saved" 2018-05-19 09:02:33 SMTP connection from [195.30.xxx.yyy]:44960 (TCP/IP connection count = 2) 2018-05-19 09:02:33 1fJvsv-0000mt-92 [212.227.17.5] SSL verify error: certificate name mismatch: DN="/OU=Domain Control Validated/OU=PositiveSSL/CN=fqdn.my-server.de" H="mx01.emig.gmx.net" 2018-05-19 09:02:33 Error while reading netlink: $VAR1 = { 'nlmsg_pid' => 3043, 'nlmsg_flags' => 0, 'nlmsg_type' => 2, 'nlmsg_seq' => 2, 'nlmsg_length' => 96 }; 2018-05-19 09:02:33 1fJvsv-0000ms-8s => info R=virtual_user T=dovecot_virtual_delivery C="250 2.0.0 MAlkHAnM/1oyCwAAIzJ5jg Saved" 2018-05-19 09:02:33 SMTP connection from [195.30.xxx.yyy]:46226 (TCP/IP connection count = 3) 2018-05-19 09:02:33 could not identify the local connection from 195.30.xxx.yyy on port 44960.

    But - how to resolve that? And how to get sending mail back to work?

    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

    OK I found the following ticket: Enabling WHM > Service Configuration > Exim Configuration Manager: "Allow weak SSL/TLS ciphers"? helps.

    I haven"t seen mess as cPanel v70, looking for alternative solution probably like Plesk as frankly having enough of v70 bugs
