I have two machines to do this experiment.
One is 192.168.2.151 in which a Thunderbird is installed.
Another is 192.168.2.139 on which there is a Sendmail running.
Just send out a e-mail from the Thunderbird whose SMTP server is set to 192.168.2.139.
Then I got the following log messages at Sendmail server.
My question is why the mail submission from Thunderbird to Sendmail is considered as RELAY?
I think RELAY should be the relation between MTAs.
Could someone help?
What kind of role does Thunderbird play here?
MUA or MTA?
