I have configured my smtp gmail server and i'm already using and sending e-mail through another application with exactly the same configuration i'm using on doku wiki smtp plugin. I'm using de TLS with smtp.gmail.com host, port 587, but having the 'Start TLS failed to enable crypto' error. Check the complete log:

Hello,

Same problem for me, using my ISP mail server (OVH). This configuration is working on my desktop and smartphone mail client (Mail) : port 587, TLS, auth with password.

On test page I've got this message There was an unexpected problem communicating with SMTP: Start TLS failed to enable crypto

With this debug log

Set: the auth
Set: a message will be sent

I'm using a docker image for my dokuwiki instance : https://hub.docker.com/r/mprasil/dokuwiki/

I tried this configuration on another dokuwiki I own (but different installation) with same result.

I figured out what's happening.

I tried to connect with a DNS TLD that was not the same than the one used in the SSL certificate.

Replacing mail.xxxx.com with hr3127649084.reseller.mis.ovh.net worked for me.

This command helped me to debug : openssl s_client -connect mail.server.com:587 -starttls smtp

@eduardo-santos can you tell me if the smtp server you configured in the plugin is smtp.gmail.com or something else ? If not try to replace your entry with smtp.gmail.com. If not, I don't have a clue of what's happening :)

eduardo-santos commented 6 years ago

@sstolz yes, it is smtp.gmail.com. Until now i can't solve the problem, so i'm using the xampp php.ini mail configuration.

I am getting the same issue, but with a pretty opaque log line in my nginx error log:

2018/12/14 17:01:57 [error] 20936#20936: *82 FastCGI sent in stderr: "PHP message: PHP Warning:  stream_socket_enable_crypto(): SSL: Success in /var/www/dokuwiki/lib/plugins/smtp/subtree/txtthinking/Mailer/src/Mailer/SMTP.php on line 201" while reading response header from upstream, client: 12.34.56.78, server: wiki.mydomain.com, request: "POST /doku.php?id=start&do=admin&page=smtp HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.0-fpm.sock:", host: "wiki.mydomain.com", referrer: "https://wiki.mydomain.com/doku.php?id=start&do=admin&page=smtp"

I don't understand why there's an error saying SSL: Success. This is with a different SMTP server (SparkPost), and sending mails from the command line with swaks works as expected:

swaks -server smtp.sparkpostmail.com:587 -tls --auth-user SMTP_Injection --auth-p
assword $PASSWORD --to $EMAIL --from noreply@wiki.mydomain.com
