    Does anyone knows these log?
    Before it was okay with the old SMTP and according to their IT Department they are using it for Lotus Notes. But now I have no idea of these crap. They have been updated their servers and using Outlook and our MFM wasn't able to send this through their mailboxes. Can anyone suggest possible solution regarding these matters?

    Have they enabled SSL?

    Do you know who their ISP is? Is the SMTP server that they are using someone other than the ISP? There are some ISPs who block all port 25 SMTP. Even if you are using SSL, I have encountered at least one ISP who blocks port 465 to any SMTP server except their own. If the SMTP server they are using is not the ISP, find out if they support any port for SMTP other than 25 and 465. GoDaddy's can use ports 25, 80, 465, and 3535. Since port 80 is also the port used for browsers, it is hard to block. One other thing, make certain that the authenication is set correctly.

    TLS is not supported for SMTP Authentication
    I would recommend configuring an Externally Secured Recieve Connector if using Exchange

    • This procedure enables the use of SMTP over SSL using Port 465 (this port
      number cannot be changed).
    • Some mail servers require that SMTP be used.
    • Most SMTP over SSL settings can only be configured via the operation
    • The only setting related to SMTP over SSL that can be configured via Web
      Image Monitor (WIM) is the Site certificate: Configuration > Security >
      Site certificate.
    • TLS is not supported.
