Hi Andreas, I can't manage it. The tools I use with my SMTP parameters work fine, but I can't get it to work with JS7, and I had the same issue with the old version of JOS. This is annoying because I don't receive JS messages in case of a problem. Is it possible to intercept the messages generated by JS in another way? Thanks.

Hi Andreas I just executed the following command: openssl s_client -showcerts -connect smtp:25 And here is the response.... This is not good!!! CONNECTED(00000154) 7556:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:ssl\record\ssl3_record.c:332: no peer certificate available No client certificate CA names sent SSL handshake has read 5 bytes and written 334 bytes Verification: OK New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE...

Hi Andreas Regarding my email server parameters: - Port 25, Authentication required with USER and PASSWORD for the SMTP server, STARTTLS must be activated I believe I have taken all these parameters into account with JS7 (see attachment) I will therefore check the certificates as you mentioned. Thanks, I will test PS: I am using a translator to switch to English. I hope to be clear in my requests and responses.

I would like to add to my previous post that when I enable - mail.smtp.starttls.enable to true I don't get the same error message. 2025-11-06T13:43:12,528 ERROR qtp590845366-22776 c.s.j.c.JOCDefaultResponse - javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target javax.mail.MessagingException:...

Hi Andreas I don't have enough tissues anymore.... I only have these parameters left (see screenshot attached) And the same error message. I removed "mail.smtp.starttls.enable = true" I use the same parameters and same data (user, password, smtp,...) for a Java program and it works I don't know what else to do.

Hi Andreas, Thank you for the tissues. Thank you for this answer, I'll check and get back to you.

Hi Andreas, I'm crying. I set authentication to true and removed the "time out".
