Question

I am trying to send an e-mail using gmail account (Delphi 7, Indy 10) with these settings:

TIdSmtp:

Port = 587;
UseTLS := utUseExplicitTLS;

TIdSSLIOHandlerSocketOpenSSL:

SSLOptions.Method := sslvTLSv1;

Everything seems to be set ok. I get this response:

Resolving hostname smtp.gmail.com.
Connecting to 74.125.77.109.
SSL status: "before/connect initialization"
SSL status: "before/connect initialization"
SSL status: "SSLv3 write client hello A"
SSL status: "SSLv3 read server hello A"
SSL status: "SSLv3 read server certificate A"
SSL status: "SSLv3 read server done A"
SSL status: "SSLv3 write client key exchange A"
SSL status: "SSLv3 write change cipher spec A"
SSL status: "SSLv3 write finished A"
SSL status: "SSLv3 flush data"
SSL status: "SSLv3 read finished A"
SSL status: "SSL negotiation finished successfully"
SSL status: "SSL negotiation finished successfully"
Cipher: name = RC4-MD5; description = RC4-MD5                 SSLv3 Kx=RSA      Au=RSA  Enc=RC4(128)  Mac=MD5 
; bits = 128; version = TLSv1/SSLv3;

And then it hangs and doesn’t finish. E-mail is not sent. What can be the problem?

Answer 1

The problem was simple. I was not patient enough and application didn’t hang, there was long timeout. The timeout was result of wrong settings.
