redirect mail does not work with external

[airbone42]

Hi,

I used the redirect all mails example with an external mail address setting:

LOCAL_RULE_0
R$*     $#smtp $@domain.com $:username

Unfortunately the mail then is neither received by the original user nor the redirected recipient. Can this be debugged somehow? It seems to work directly relying on sendmail -bt

Tobias.
