What do the parts of the MailMessage.Id mean, e.g. for an IMAP message?
00990...$1ad5...$508...$@gmail.com
Will the message ID be identical when retrieving the same email at a later point in time?
Another question in the same context:
Is ImapClient.SearchMessageUids returning a list of the above MailMessage.Ids? Or rather IMAP message UIDs (like 32424) converted to a list of strings?
Hi Thomas,
Yes.
No, these two values don’t represent the same thing.
The MailMessage.Id is a globally unique identifier. See the specification of Content-ID Header Field, the same rules apply to the message’s ID.
On the other hand, the ImapMessageInfo.Uid is unique within a mailbox (a single email account), see the Unique Identifier (UID) Message Attribute.
I hope this helps, let me know if you have any questions.
Regards,
Mario
