Hola,
I have some scanners and some Outlook users that do want to use SASL to be able to send mail.
However, seems tcp/465 and 587 along with the specific stuff to make it work in EFA are not configured.
for details see http://www.postfix.org/TLS_README.html
I enabled this is master.cf and main.cf, but I am not sure if I set this up correctly.
I updated iptables to allow the ports, I adjusted master.cf to allow submission and smpts (on both enabled sasl and in smtps wrapper mode).
Is there anything more I should do? I 'd be happy to post my main.cf and master.cf and would be great if anyone can shine a light here. If this is the way to go, we can put it in next version of EFA.
Grtz,
Ronald
