Hi Terry,
How can I allow e-mails to be sent from my website to external users
(like GMail) but not be an open-relay to spammers?
By default Postfix will deliver mail to it's intended destination
(GMail, AOL,
etc.). but will accept mail only from IP addresses in "mynetworks".
Sorry, I replied without fully reading the message.
What you're looking for requires that your email interface (webmail,
forms,
etc) only accept mail from authenticated users. This would typically
be a
function of your website, not postifx. The sending application would
then need
to authenticate with Postfix, or be part of MyNetworks.
Well, I have a ColdFusion based website that I have a few forms that
users submit to sign up for events. So they dont log in or anything. I
specified localhost in <CFMail> and it works for domains on my system,
but when I send the user a copy of what they submitted they dont get it.
My main.cf says:
mynetworks = 172.16.254.0/28
That address is my apartment. I am hosting this at mosso so I have one
static from them of 67.23.34.37. Mail and CF run on this same IP.
