Hello Everyone, 

i'm getting this error when FIM tries to send an email, 

i'm gessing its an exchange issue but does anyone have an idea on how to solve it ?

below is the configuration i'm using

<add key="mailServer" value="smtp.xxx.net" />
    <add key="isExchange" value="0" />
    <add key="sendAsAddress" value="svc_PRO_FIM_PORTAL@xxx.com" />

thanks  !

When you use the config <add key="isExchange" value="0" /> FIM tys to send mail with SMTP on port 25.

Do you're exchange serve allow relay form the fim server?

Can you send a mail with ex. Telnet frome the same address?

silly anti spam problem 

thanks anyway :)
