Hi,
I need to configure Postfix to be an open relay on a specific port,
lets say 3326. I already have Postfix configured like a normal
mailserver that requires authentication etc. but I need it to not ask
for authentication on port 3326. How do I do this?
I know this isn't safe but this port wont be open for the internet,
just specific IP's that I specify on my router, so I wont be a target
for spammers.
I already have port 3325 open just like port 25, I did that by just
adding this to /etc/services:
smtp2 3325/tcp
and in /etc/postfix/master.cf:
smtp2 inet n - - - - smtpd
So I can do the same for port 3326 but I don't know how to disable the
authentication part. How can I do this?
Thanks,
-Patric
It would actually be easier if there's a way to accept hostnames
(mail.example.com) directly on the standard ports without
authentication. I use 'mynetworks' to allow different IP numbers to send
mail without authenticating but it doesn't support
domain-names/hostnames. Or maybe there's another way it should be done?
All I actually need to do is to allow a dyndns-adress to send without
authentication.
