System.Net.Mail.MailAddress不允许Gmail GROUP联系人

Question

I am using a Gmail business account, say noreply@mycompany.com to send a daily email reports to a few of my clients whose email addresses are from different domains. I use C# to send my email to Gmail's SMTP server.

var receiver = new MailAddress("receiver@domain1.com");
var receiver = new MailAddress("receiver@domain2.com");
var receiver = new MailAddress("receiver@domain3.com");

After a while I found out I had to modify code every time a new customer demands email report. So I want to make a group and maintain that group. Gmail has a Add Group settings in your account's "Contacts" page so I used that to create a group named ReportGroup and added those people. And in the code, this lines throws exception:

var receiver = new MailAddress("ReportGroup");

saying The specified string is not in the form required for an e-mail address.

Well apparently this isn't a legit email address. Is there a way I can bypass this format check? Or is it doesn't make sense to do so?

In further attempts, I tried to name my group as reportgroup@mycompany.com . This time the email got sent without complain however the gmail server rejects the receiver, claiming that

50-5.1.1 The email account that you tried to reach does not exist. Please try
550-5.1.1 double-checking the recipient's email address for typos or
550-5.1.1 unnecessary spaces. Learn more at
550 5.1.1  https://support.google.com/mail/answer/6596 ai2si23882633pad.98 - gsmtp

So this isn't the way to go either. Could any one suggest a solution for me to allow someone non-programmer to maintain an receiver list to which my code sends report to?

Answer 1

Create an alias for your group, and then send email to that address. Then you can continue to maintain the group as you normally do.
