Hi all I've a nlb cluster of exchange 2003 frontends and two backends in cluster server. When the internal clients connect to the backends directly, everythings works good. I've enabled secure imap and secure smtp on the frontends to allow external users use the mail. Imaps works flawless but not smtp. When sending to external users, the message is sent correctly. If a message with a local recipient is sent, it is enqueued as a unreachable destination !?!?!?! Whats could be the problem? Thx all!!
Do you have a smart host configured in your SMTP virtual server? If so, remove it and create an SMTP Connector and specify the smart host there. -- Ed Crowley MVP - Exchange "Protecting the world from PSTs and brick backups!" wrote in message news:f033c74d-1c7c-4339-ae7d-669c9c60cb69@a70g2000hsh.googlegroups.com... > Hi all > > I've a nlb cluster of exchange 2003 frontends and two backends in > cluster server. > > When the internal clients connect to the backends directly, > everythings works good. > > I've enabled secure imap and secure smtp on the frontends to allow > external users use the mail. > Imaps works flawless but not smtp.

Ive redirected the generated NDR to an external account to receive it: NDR says: "This message was rejected due to the current administrative policy by the destination" On 3 jul, 02:26, "Ed Crowley [MVP]" wrote: > Do you have a smart host configured in your SMTP virtual server?
