    Code:
    " An error occurred while sending mail. The mail server responded: 
Please turn on SMTP Authentication in your mail client.  ([192.168.0.109])
[106.51.xxx.xxx]:58114 is not permitted to relay through this server
without authentication..
 Please check the message recipient "someusr@gmail.com" and try again. "
    It happing with different domain same issue.

    your clients do not have
    SMTP Authentication on

    Have them enable on their email client
    or in tweak settings mail check the box

    Allow users to relay mail if they use an IP address through which someone has validated an IMAP or POP3 login within the last hour (Pop-before-SMTP)

    @dalem is correct they aren't authenticating properly - what happens if you select "use the same settings as incoming server" under "my outgoing server (SMTP) requires authentication"
