Hello, again Untrusted user Feb 2 18:03:21 mail postfix/smtp[19647]: certificate verification failed for ar.vmx.terra.com[208.84.244.136]:25: untrusted issuer /C=US/O=Sample, Inc./OU=IT Team 20160319112329 /CN=CA How to avoid untrusted user and connections, when using Certificate ? Thanks Nestor Mazza
You seem to use a self-signed SSL certificate. To get rid of the error, you need a officially signed ssl cert. You can get ne from Let's encrypt for free like this: https://www.howtoforge.com/communit...cates-into-ispconfig.71055/page-7#post-355116 Then configure Postfix to use it: cd /etc/postfix mv smtpd.cert smtpd.cert_bak mv smtpd.key smtpd.key_bak ln -s /usr/local/ispconfig/interface/ssl/ispserver.crt smtpd.cert ln -s /usr/local/ispconfig/interface/ssl/ispserver.key smtpd.key
