Hello,

About 2 months ago, hschneider helped me to set up a LAN Xmail server. It was working fine until 2 days ago, when my client Outlook Express returns the following error (no changes have been made to the settings of the server):

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'dan@mondo.net'........Protocol: SMTP, Server Response: '550 5.7.1 Unable to relay for dan@mondo.net', Port:25.......... Server Error: 550, Error Number: 0x800CCC79

Please give me an opinion of what is wrong.
Thank you.

Maybe the mondo.net server has blacklisted you. Any details in the undelivered message's SLOG ?

No... no blacklist. It is an intranet and I am the administrator.

Outlook express can check for new messages (can receive mail) but cannot send mail. This is the problem. Can you help me?

Oh, and I forgot to mention: when I use Query from XMail Queue Manager, there is no message returned, the screen remains blank.

mondo.net is not an intranet:

telnet mondo.net 25
Trying 207.139.87.11...
Connected to mondo.net.
Escape character is '^]'.
220 X1 NT-ESMTP Server www.mondo.net (IMail 4.07 95501-1)

This is your recipient server and it does not allow you to relay.
Are you the admin of exactly this machine ?
