如何修复Chilkat ActiveX SendEmail错误

问题描述

使用Delphi Chilkat ActiveX。

我的IMAPS和TChilkatMailman（Mailman）连接成功。

Mailman.SMTPConnect和MailMan.SMTPAuthenticate都返回1，所以我认为我的连接很好。

这是我的delphi代码：

email2    := TChilkatEmail.Create(Self);
email2.Subject := 'Test Email';
email2.From    := '[e-mail]';
email2.AddTo('simon wood','[e-mail]');
email2.Body := 'An Email Body';
email2.Sender := '[e-mail]';
mailman.SendEmail(email2.ControlInterface);

LastErrorText产生：
