Trying to test mail from sendmail to mailserver. Syntax used is
./sendmail -s 'SmartView' -t MAILSERVER -f SENDER_EMAIL_ADDRESS RECEIVER_EMAIL_ADDRESS
I have used fwmonitor to capture output and opened it in Wireshark. It goes like this:
220 answer from mailserver
250 reply from mailserver
And then it stops. The next thing should be something like this from sendmail
MAIL FROM: firstname.lastname@example.org but it never happens.
Anyone knows why and if there is something wrong with the syntax used?
