Hello Team,

I am using 123reg email server for sending emails for my Redmine. Recently they have a new SPF record update and after some time my emails from Redmine is not going out and the log showing the below error message.

Email delivery error: hostname "" does not match the server certificate
= Running shared code for Issue (#33073) "Auto_CRM #33073: redmine email issue 10" 

I have tried all the port settings.
secure/SSL option: ON outgoing port number: 465 and SSL option Off for port numbers 25 and 587. But all the time receiving the same error and I am not receiving emails.
