Failed comunication Antispam @SSP - Zimbra MTA [8.6]

Postby afreidme » Wed Jan 10, 2018 7:08 pm

Hello everyone,
First of all some informations:

Zimbra Version: zcs-8.6.0_GA_1153.RHEL7_64.20141215151110
ASSP Version: 2.5.5(17223)


I'm trying to setup a zimbra server (Each server with one of these services LDAP-MX-IMAP-NGINX) with @SSP as a antispam. All redirects on Firewall done and send email to external domains is working, but, when i try to send email from external to internal the @SSP can't connect to MTA port 25. I'm trying to send from a webmail to a webmail. Some Logs:
FROM ASSP: [Worker_4] [TLS-out] info: can't read any data from socket XXX.XXX.XXX.XXX:25 - Connection reset by peer

FROM MTA:
Jan 10 15:39:14 mta postfix/smtpd[7647]: SSL_accept error from <A entry from antispam> [Antispam-IP]: -1
Jan 10 15:39:14 mta postfix/smtpd[7647]: warning: TLS library problem: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol:s23_srvr.c:647:
Jan 10 15:39:14 mta postfix/smtpd[7647]: lost connection after STARTTLS from <A entry from antispam>[Antispam-IP]
Jan 10 15:39:14 mta postfix/smtpd[7647]: disconnect from <A entry from antispam>[Antispam-IP]


PS: I have the same setup running in other environment and it works fine, but i'm using a new version of ASSP in CentOS 7 instead Ubuntu

can u guys help me to figure out this problem? i've googled a lot and nothing.

Reggards.
