Our local server is not receving any outside email directly, it is received
by fetchmail in multi-drop mode from Europe based Server which is official
MX.
Do you mean to say fetchmail will also not be able to multi-drop email to
this smtp ?
Let me clarify situation again:
Our domain is in Europe and we are having a local email server to fetch and
distribute incoming emails. The outbound emails from my network are
collected by same machine and then sent to my ISP's relay smtp.
Now what I want to do is that all outbound email submitted to my local smtp
server should be authenticated nefore accepting. This way my teammates who
are travelling can also use this machine as smtp server otherwise my smtp
shall be spammed.
