I have a own website and when I want to use the mail server with a valid account to send mail from the website gives me the following error:

Aug 10 12:02:10 mail1 postfix/submission/smtpd[3869]: lost connection after STARTTLS from unknown[192.168.100.28]
Aug 10 12:02:10 mail1 postfix/submission/smtpd[3869]: disconnect from unknown[192.168.100.28]
Aug 10 12:02:49 mail1 postfix/submission/smtpd[3892]: connect from unknown[192.168.100.28]
Aug 10 12:02:49 mail1 postfix/submission/smtpd[3892]: SSL_accept error from unknown[192.168.100.28]: 0
Aug 10 12:02:49 mail1 postfix/submission/smtpd[3892]: warning: TLS library problem: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:s3_pkt.c:1300:SSL alert number 48:

the web server and mail server are through the internal network, so it appears the ip 192.168.100.28 (webserver), in the script on page I use TLS connection port 587 with a valid email account

Re: send mail from website - error TLS

Make sure your website supports sending email with STARTTLS.

Re: send mail from website - error TLS

there any way to test if it supports this connection?

Re: send mail from website - error TLS

*) Check the code to see whether it actually performs STARTTLS smtp command. According to the log in your first post, your website doesn't support it, or you didn't correctly configure it to perform STARTTLS.

*) Ask your software vendor (website developer) for support to make it clear.
