dear ZhangHuangbin!

My iredmail 0.8.7 is fresh,new installation, and iredadmin ldap backend.
I'd like use smtp secure tls 587 port and nosecure 25 port.The older iredmail version it's worked with the settings below.
When i send messages in 587 port it's ok, but I use no sesure 25 port I have error massages thunderbird.
The mail server responded: 5.7.1
Sender address rejected: not logged in

In a mail.log
postfix/ssmtpd[20539]: NOQUEUE: reject: RCPT from unknown[x.x.x.x]: 553 5.7.1 <x.y@z.com>: Sender address rejected: not logged in; from=<

I change main.cf
cat main.cf |grep may
smtp_tls_security_level = may
smtpd_tls_security_level = may

and I try other non secure port add a line in master.cf
