Can't change topic in notification mails

I can't change the topic in the notification emails

no watter what i write inside the "topic" field acronis decided to change it to "True Image Notification" when sending test mail or names it after the backup task
without this feature i am not able to filter these mails correctly

After the buggy implementations in the previous versions (test fails, but notifications still arrive. email adress has to be set in angle brackets. etc.) i did not expect much. sending mail can be tough

PS: Is it possible to send the logs in *.txt format with another tool that actually can do it? like blat?
