Send Email

I have a function that sends email. When I compile the project for widows, the email is sent correctly. But when I compile for Linux, I come across the following error:

EOpenSslNetTls {LastError:1,OpenSsl:"1010117F",Message:"TOpenSslNetTls.AfterConnection connect: OpenSSL 1010117F error 1 [SSL_ERROR_SSL (error:1416F086:SSL routines:tls_process_serve r_certificate:certificate verify failed) (unable to get local issuer certificate #20)]"} [TAppRestHttpSrv8081v1THttpSrvRe] at 6ea87f 00000000129308CA EXC ENetSock {Message:"TCrtSocket.DoTlsAfter: TLS failed [EOpenSslNetTls TOpens 6c922f

In the email sending settings, I set TLS to 1. Am I missing something?

Does have the smtp server a valid X.509 certificate, known by the client host?

Thanks now works. Can u explain about this change? Or by default sendmail should be ignore certificate?

My guess is that on Windows, you did have the information about the SMTP server certificate into your system, whereas with OpenSSL, you did not.

But it seems unsafe that SendEmail() would always ignore the certificate.
I have added a new optional TLSIgnoreCertError parameter:

Ensure you set TLSIgnoreCertError = true for your server.

It works! Thank you A.B!!

In linux, `/etc/ssl/certs` stores trusted certificates, including CA's. But in Windows, I don't know how to make openssl work to verify the tls cert. Therefore, it is recommended to use SChannel as the TLS layer in Windows, and OpenSSL is preferred in Linux.

Hi guys,

All works in windows 10 but dont work on linux unbuntu 21 with same configurations.

What i should have on linux to sendmail works with ou without TLS?

Please define "don't work".
Is it a certificate issue?

linux without certificate installed, resolved problem!
