DelphiXE10.1BerlinIndy发送QQ邮件
突发奇想, 如果服务在运⾏过程中, 出现某些问题, 需要提醒管理员时, 就发⼀封邮件出来, 在⽹上也了些资料, 学习了下使⽤Indy发送QQ邮件.
发件⼈我⽤的QQ邮箱, 关于这个, QQ邮箱需要进⾏⼀些设置, 进⽽获取授权码.
QQ邮箱设置可参考:
获取授权码后, 当邮箱密码⽤即可.
代码如下:
unit Unit1;

IdMessageClient, IdSMTPBase, IdSMTP, IdMessage, IdIOHandler,
IdIOHandlerSocket, IdIOHandlerStack, IdSSL, IdSSLOpenSSL, IdSSLOpenSSLHeaders;

end;
procedure TForm1.FormDestroy(Sender: TObject);
begin
if Assigned(fIdSSL) then
FreeAndNil(fIdSSL);
end;
initialization
iResult := IdSSLOpenSSLHeaders.Load();
end.
点击发送后, 收件⼈收到:
需要注意的是, 使⽤了SSL的两个dll⽂件(libeay32.dll, ssleay32.dll). 这两个⽂件需要根据开发⼯具的版本去对应的.
