Hi

Microsoft Exchange 2000 Server

|||Seems that the server is blocking the sender / rcpt combination. Some MailServer are configured not to accept outgoing mails to certain mail domains. If you are in charge of the mailserver, look at the blacklist if the hotmail domain is on the blacklist or ask your administrator to do this.

I don't think so, because I can send correctly using another applications with the same Mail Server.

Using Outlook Express for example.

Any tip?

Thanks,

Lets clarify some things. If anything is not right, you should correct me to find the problem.

The Exchange server is inside your company, allowing SMTP relay.
You are using an account to send the emails out which is known and trusted on the SMTP server.
Your Exchange server is allowing SMTP relay with no constraints on other mail domains like hotmail.

if the above assumptions are right, you should be able to send mails to an outside mail domain, Outlook Express normally does not connect to the Exchange Server unless you allow SMTP and POP access o the mailboxes, so I guess your mailserver for sending out Outlook Express mails is anothr than the Exchange Server.
