Hello, I am trying to setup stunnel to send email using gmail smtp server trough Oracle Database. I first tested on my windows machine. I installed and configured stunnel and it worked fine.But now I tried to do the same on our server (RHEL 6.4) and it doesn't work. I can successfuly telnet the 25 port: [root@server1 stunnel]# telnet localhost 25Trying 127.0.0.1...Connected to localhost.Escape character is '^]'.220 mx.google.com ESMTP so2sm18740691pbc.5 - gsmtp When I send the email, i receive this error: SMTP permanent error: 534 5.7.14 54 ef10sm21262349pac.1 - gsmtp anyone have any idea?
the stunnel.conf: pid = /stunnel.pidoutput = /var/log/stunnel.logcompression = zlibsslVersion = alloptions = NO_SSLv2debug = 7 [gmail-smtp]client = yesaccept = localhost:25connect = smtp.gmail.com:465
