hi
all my domain with Outlook 2007 can't send email with error :
your server does not support the connection encryption type you have specified bla bla bla.
I've tried with all port (25, 465 and 587) with None, SSL or TLS but still failed.
this is last log /var/log/maillog :
Jan 30 19:52:20 vps postfix/smtpd[15278]: connect from unknown[xxx.xxx.xxx.xxx]
Jan 30 19:52:20 vps postfix/smtpd[15278]: SSL_accept error from unknown[xxx.xxx.xxx.xxx]: -1
Jan 30 19:52:20 vps postfix/smtpd[15278]: warning: TLS library problem: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol:s23_srvr.c:640:
Jan 30 19:52:20 vps postfix/smtpd[15278]: lost connection after STARTTLS from unknown[xxx.xxx.xxx.xxx]
Jan 30 19:52:20 vps postfix/smtpd[15278]: disconnect from unknown[180.251.229.202] ehlo=1 starttls=0/1 commands=1/2
but from Outlook 2016 there's no problem with port 465 SSL or 587 STARTTLS, can't send if using 587 TLS
I've tried changed in /etc/postfix/main.cf but still failed, anyone can help me please.
I'm using Plesk Obsidian 18.0.33.0
thank you
Fahmi
