nmsmtp属性中的抄送人最多可有多少个？受什么限制？(200分)

听

应该没有吧，不过，还是建议用SakMail，有源码，想知道什么直接看源吗就可以了

好象这些属性都是string类型的，应该放不了多少个地址的,delphi的帮助中是这样说的。不过如果是2Gb的话，能不能发出去呢？
shortString 255 characters 2 to 256 bytes backward compatibility
AnsiString ~2^31 characters 4 bytes to 2GB 8-bit (ANSI) characters
WideString ~2^30 characters 4 bytes to 2GB Unicode characters;
COM
