Sets a new unique value of Message-ID header and returns it.

Parameters

domain

The domain name to be put in the MessageID field. If a null reference or an empty string, the local computer name is used.

Return Value

A string containing the new unique value Message-ID value (without angle brackets).

Remarks

Message-ID value is composed of the current thread ID + "." + the random string + "@" + the domain name. This value is assigned to MessageID property. Also, MailBee encloses it with angle brackets (<>) and puts it into Message-ID header value.

You can set Message-ID value manually using MessageID property.

Note   MailBee automatically sets unique Message-ID value when the mail message is being sent (or submitted to the pickup folder) unless MailMessage.Builder.SetMessageIDOnSend property is set to false.
