Adding SSL/TLS to SMTP Email Sending

[paulcoshott]

Hi Remy,

Thanks for the help. I've done what you've instructed and I'm getting an error which seems to be based on the SSLVersions value I am choosing. I downloaded libeay32.dll and ssleay32.dll from https://indy.fulgan.com/SSL/
I wasn't sure which version to download, so I just went for the latest 32bit one. File name : openssl-1.0.2o-i386-win32.zip

Some details on my system:
Windows 64bit
My application 32bit
Delphi XE6
Indy version 10.6.0.5122
Using Port 465
TIdSMTP.UseTLS = utUseImplicitTLS
TIdSSLIOHandlerSocketOpenSSL.SSLOptions.Method = ssImUnassigned

I put the dll's in my application folder.

I tried each of the versions, and the following show the error I got with each one.

Version and it's error:
SSL v1 error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version
SSL v1_1 error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version
SSL v1_2 error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version
SSL v2 ERROR: Error creating SSL context
SSL v3 error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version
SSL v23 error:140770FC:SSL routines:SSS23_GET_SERVER_HELLO:unknown protocol

I can't make a connection with version 2. All other versions connect and authorisation is successful, but can't send an email, due to above error.

Any ideas?

Thanks heaps for the help,
Paul
