Setup domain name for email's message-id

Question

Our mail.dll sets up "mail.dll" as hostname in part of the email message id, e.g. Message-ID: 70e6f0cf-cc46-40d5-a139-8365a70631aa@mail.dll.

I would like to change this part to another domain. Is this possible?

You can use MailBuilder.MessageID property to set mail's message-id header yourself:

var builder = new MailBuilder();
builder.MessageId = Guid.NewGuid() + "@example.com";
....
IMail email = builder.Create();
