I am getting this error when sending mail from both my local host and web server:
Syntax error in parameters or arguments. The server response was: 5.7.1 <firstname.lastname@example.org>... Permission Denied
On the client.send:
Dim client As New SmtpClient()
the from and to addresses are valid.
This is what I have in my web.config:
<smtp deliveryMethod="Network" from="email@example.com">
<network host="mail.xxx.net" port="25" userName="xxx" password="xxx"/>
I have also tried the host as the actual IP address for the mail server too.
I do have a firewall. the mail server is setup in the firewall and is very actively in use, but from another web server with asp classic pages.
I have a netgear firewall.
So there are 3 servers, web server 2000 which sends mail fine, web server2008 which is new and hasn't yet sent mail, and mail server.
What am I lacking?
I don't know what deliveryMethod I should use. Saw it in an example.
