Plz Help : buildaddr: unknown mailer smptp

[Azher Amin]

Dear Team,

I tried to install Mail Scanner, SpamAssassin, ClamAV and ClamAV PERL
Module. I had some problem with LANG in my redhat 9 system, but I set the
LANG=C then all seems to install.

However when I try to send email from outside to this server it bounces the
mail with the following error. Can you plz guess what can be the error.

Regards
Azher
