If I understand this correctly: The implication is that SAP send an anonymous request to POSTFIX though SMTP service? then POSTFIX can use the request for sending e-mail to client.We really want to know this? According to some web searchers, SAP has an SMTP client implementation. To send mail without authentication you could execute as root on the Postfix server: # postconf "mynetworks = $(postconf -h mynetworks) x.x.x.x" # postfix reload Where x.x.x.x is the IP address of the SAP machine. This will accept mail from the SAP machine with any sender or any recipient address. Wietse
