I am facing some problems in configuring the inbound mail system. I tried using telnet to check whether mails are received in SOIN. I am able to connect to the SAP server via telnet but at the end after composing the entire mail and putting the period, i am getting an error back saying "554 transaction failed"
I have done all the required inbound configurations in transaction SICF. Also put a an ID with SAP_ALL authorizations.
