Question:

Email using MailMan: Attachment in utf-8 send as ANSI.

Feb 14 '14 at 09:19

Hello,

I'm using MailMan to send an email with a file attachment that is encoded in utf-8 without BOM. I'm using the following code to send the email.

MailMan client = new MailMan();
//...Configure...
Email email = new Email();
email.FromAddress = fromAddress;
email.AddMultipleTo(recipients);
email.Subject = "Subject";
email.Charset = "utf-8";

//email.AddFileAttachment2(localErrorFileName, "text/csv; charset=utf-8");
email.AddFileAttachment(localErrorFileName);
email.SetAttachmentCharset(0, "utf-8");

client.SendEmail(email);

Just before sending the email, this email.GetMime() returns

But when I see the email source from the email client (Thunderbird) I get this:

Notice the difference in the email attachment contents. Sent as utf-8, but received as ANSI. Am I missing something?
