我正在尝试使用这些设置使用gmail帐户(Delphi 7,Indy 10)发送电子邮件：
TIdSmtp：
Port = 587; UseTLS := utUseExplicitTLS;
TIdSSLIOHandlerSocketopenSSL：
SSLOptions.Method := sslvTLSv1;
一切似乎都设置好了.我收到了这个回复：
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;
然后它挂起并没有完成.电子邮件未发送.可能是什么问题？
解决方法
是的,我已经看到了indy10和tls(通常是gmail)的很多问题.
首先确保你有最新的ssl库from here
我已经看到间歇性的失速和错误已经在indy的最新版本中得到解决(即非稳定释放).见http://www.indyproject.org/sockets/download/svn.DE.aspx
对于gmail,我通常在端口465上使用implicityTLS ..
idSmtp := TIdSMTP.Create(nil);
try
idSmtp.IOHandler := nil;
idSmtp.ManagedioHandler := true;
// try to use SSL
try
TIdSSLContext.Create.Free;
idSmtp.IOHandler := TIdSSLIOHandlerSocketopenSSL.Create(idSmtp);
if (smtpSettings.port = 465) then
idSmtp.UseTLS := utUseImplicitTLS
else
idSmtp.UseTLS := utUseExplicitTLS;
except
idSmtp.IOHandler.Free;
idSmtp.IOHandler := nil;
end;
if (idSmtp.IOHandler = nil) then
begin
idSmtp.IOHandler := TIdioHandler.MakeDefaultIOHandler(idSmtp);
idSmtp.UseTLS := utNoTLSSupport;
end;
// send message,etc
finally
idSmtp.Free;
end;
