Hi all... I don't know why, but my Exchange2k does not send email to some domains. Wen I try send a email to xxx@xxxxxxxxxx; yyy@xxxxxxxxxx and zzz@xxxxxxx, my smtp queues display a green folder to uol.com.br and aol.com. But to domain bol.com.br the connection state display "retry". Does n1 can help me? Tnks! Rafael Rodrigues.
