Hi, I am having problems sending email from SBS 2003 using Exchange 2003.
I am getting the following message when try to send email:
The following recipient(s) could not be reached:
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<mail.domain-name.net #5.5.0 smtp;550-5.7.1 [xxx.x.xxx.xx] The IP you're using to send mail is not authorized to>
The IP address is Static,
Or anyone knows how to configure to MS Exchange 2003 to send email via ISP smtp server??
Thanks for help.
