I set the idSMPT1.IOHandler:=IdSSLIOHandlerSocketOpenSSL1; idSMTP1.UseTLS:=utUseExplicitTLS; and put the Indy Open SSL libraries ( libeay32.dll and ssleay32.dll from http://www.intelicom.si/www.nsf/docs/6GERPJGIBC?opendocument&cat=9&doc=6GERPJGIBC&lang=en ) in the same directory as my application. It works. My question is, is there any way tospecify what directory to look in for the dll's ? is that what TIdSSLIOHandlerSocketOpenSSL.SSLOptions.VerifyDirs is for? I'd like to be able to specify, b/c whatt if I want to use openSSL for other things in the application? I'd like to use the newer dll's.

Quote: is there any way tospecify what directory to look in for the dll's ? No. Indy does not specify any folder name when loading the DLLs, so they must exist in the OS's search path. Refer to the documentation for the Win32 API LoadLibrary() function for a list of rules that the OS follows when looking for DLLs with no folder names specified.

Quote: b/c whatt if I want to use openSSL for other things in the application? I'd like to use the newer dll's. You must upgrade to the latest Indy 10 snapshot in order to use newer DLLs. The DLLs you are using right now are 4 years old, and are not official DLLs from http://www.openssl.org anyway. Until recently, Indy had had to always use custom-built DLLs because it could not use the official DLLs. So updates were released whenever someone could get around to re-building the custom DLLs with the latest OpenSSL version at the time. So Indy was usually far behind in OpenSSL updates/fixes. Recently, Indy 10 was updated to fully support the official DLLs. The custom DLLs are no longer used at all. This way, people can stay up-to-date with the official DLLs whenever new versions are released on http://www.openssl.org.

I thought I had the latest Indy version (10.0.52) -I will try to figure out how to get the beta version.
