Problem Details
In cases it is not possible to configure outgoing SMTP authentication on the E-Mail server, following possible solutions are available:
- Use a local E-Mail client like Mozilla Thunderbird or Microsoft Outlook to send Fax E-Mails directly to the Faxserver using SMTP Authentication
- In case your Faxserver is operating in a secured network, it is possible to change settings on the Linux AP hosting the Faxserver in order no SMTP authentication is required for inbound connections.
Use an SMTP-Client on Users PC
Usually E-Mail client applications, like Mozilla Thunderbird or Microsoft Outlook, are able to send E-Mails via SMTP with authentication. In Thunderbird it is possible to add an additional SMTP Server, and in Outlook an additional Mail Account pointing to the Faxserver as SMTP Server.
Configuration with disabled Authentication
At the moment only manual change of the configuration files on Linux is possible to disable SMTP Authentication:
For the first you have to put the IP address of the SMTP server under /etc/postfix/main.cf
:
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 172.31.9.10
E.g. 172.31.9.10at the end of the line is my SMTP server.
The second file to change is /var/mail/vhosts/catchall.faxserver/.dovecot.sieve
The original file contains:
require ["variables"]; if header :matches "Received" "*(Authenticated sender: *)*" { redirect "${2}@redirected.faxserver"; stop; } else { discard; }
The line with "discard;" must be changed to "redirect "default@redirected.faxserver"; stop;" , like this:
require ["variables"]; if header :matches "Received" "*(Authenticated sender: *)*" { redirect "${2}@redirected.faxserver"; stop; } else { redirect "default@redirected.faxserver"; stop; }
It is important to match "default" with the User of the Mail Configuration of the Faxserver. So the Name of the SMTP User is used in this example was "default".
