Business Connector question

[neih2lille]

hi,
I use sysmailer class to send mail with Exchange 5.5 (without
authentification), everything works perfectly.

yesterday, my network admin modifies an exchange parameter which
consists in being authenticated to use exchange, since I do not manage
more to send the mail from axapta.

I tried to bring a user and a password to the level of the
of screen email parameter, but apparement Axapta is unaware of
these parameters, anyone has this problem before? how Axapta pass
parameters user and password to Exchange?

-question is in axapta the Email parameters (account and password
name) what is the use of?

thanks for your helps.

yannick.
