使用SMTPClient发送传真？

[英]Sending Fax using SMTPClient?

原文 2010-08-10 07:24:17 7 2 c#/ email/ exchange-server/ fax

We have a exchangeserver configured to send the attachment of a email as fax if the the "to-address-field" is in the format [fax:user/company@faxnumber] (used internally). 如果“ to-address-field”的格式为[fax：user / company @ faxnumber]（内部使用），我们将Exchange Server配置为以电子邮件形式发送电子邮件附件。 It works when I send manually from Outlook. 当我从Outlook手动发送时，它可以工作。 But how can send an email with to-address as above using Smtpclient? 但是如何使用Smtpclient发送带有上述收件人地址的电子邮件呢？

Is it possible to suppress the emailaddress validation? 是否可以禁止电子邮件地址验证？ at the moment i get this error: "System.FormatException : The specified string is not in the form required for an e-mail address." 目前，我收到此错误：“ System.FormatException：指定的字符串不是电子邮件地址所需的格式。”

I'm fairly sure that it's not possible. 我相当确定这是不可能的。 However, at least in .Net 4.0 (which is less restrictive than earlier versions), everything except the : is fine though. 但是，至少在.Net 4.0（比以前的版本没有那么严格的限制）中，除:之外的所有内容都可以。 Maybe you could get the admins to change the SMTP server to support other characters than : after the string fax ? 也许您可以让管理员更改SMTP服务器以支持除以下字符之外的其他字符:字符串fax ？

For example, maybe you could use fax= instead. 例如，也许您可以改用fax= 。

It is not possible through the SmtpClient. 无法通过SmtpClient。 If fax=asdfasdf is wanted then going through interop.outlook.dll is needed. 如果需要Fax = asdfasdf，则需要通过interop.outlook.dll。
