Hello, I just installed Xeams on my laptop to test it out. I have configured the settings in Windows Live Mail on the laptop to just access/send/receive mail. However I can send mail to external mail users such as gmail. However on the gmail side I can't send emails to the server. All I get when gmail returns the email is this: The error that the other server returned was: 5.1.1 Recipient address rejected I have read on a Zimbra fourm that you can disable smtpd_reject_unlisted_recipients. Thanks.
