I am trying to send a mail with a non root user (also by tuleap application) but i have some trouble.
when we use a root user with command
echo “TR : This is a test of sending mail” | mail -s Test <mail>
it return this log and my email is sent
Mar 10 16:59:09 localhost sendmail[11969]: t2AGx9Up011969: from=root, size=258, class=0, nrcpts=1, msgid=<[email protected]>, relay=root@localhost
Mar 10 16:59:09 localhost sendmail[11970]: t2AGx9Js011970: from=<[email protected]>, size=521, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA, relay=localhost [127.0.0.1]

Mar 10 16:59:15 localhost sendmail[11972]: t2AGx9Js011970: to=<my mail>, ctladdr=<[email protected]> (0/0), delay=00:00:06, xdelay=00:00:06, mailer=relay, pri=120521, relay=<my SMTP server> [IP], dsn=2.0.0, stat=Sent (OK id=1YVNUv-002ihW-JJ)
but when we use an other use (like codendiadm as used by tuleap) with the same command, it return this log without sending mail

Try to remove sendmail and install postfix instead. And tell me if it works better this way. You'll find how to do it here.
