I wonder how and where the email-address is built that sendfax uses in notifications.
If I insert %email_f in the sendfax-string, an email-address is used which I don't
know where it comes from.
If I don't specify %email_f in the sendfax-string it seems that the username
of the logged in user and the hostname is concatenated and used as email-address.
Where does sendfax takes this email-address from when %email_f is specified?
I hope this is not offtopic and it would be great if someone could answer
