Working with the NULL Sender Address

[jhumphries83]

Hi,

A quick question - how should I be working with the NULL Sender address in MimeKit?

Back in v1.10 I was able to create an instance of the NULL Sender address like this:

public static MailboxAddress NullMailboxAddress
{
     get { return new MailboxAddress(string.Empty, string.Empty); }
}

However, in v1.16 I receive a ArgumentException when doing this.

I want so be able to send a DSN from the NULL Sender by doing something like this:

smtpClient.Send(bounceMessage, EmailAddress.NullMailboxAddress, bounceMessage.To.Mailboxes);

Thanks!

I should also mention that I've tried:

return new MailboxAddress(string.Empty, "<>");

but that throws a ParseException

SMTP requires a sender address. You don't have to add it to the message, though.

never mind, I guess it is allowed.

Hi, Thanks for fixing that so quickly - I'm able to create an instance of the MailboxAddress with an empty address now, but when I call MailKit.Net.Smtp.SmtpClient.Send I'm getting the exception "Index was outside the bounds of the array" at MimeKit.InternetAddress.TryParseLocalPart.

Again, I think this worked back in v1.10 - but now it validates the sender address when calling that method. I'm wondering whether the NULL sender address should be treated as a special case and have a check for that up front when validating the sender?

I took a look at the code but it wasnt clear to me where the validation was happening.

It should work now.

Thanks for getting this sorted so quickly. Do you have a plan for the next release date yet?

End of May I guess. I've been really busy and don't have time to make a release right now.
