c# - What is the unique identification for emails? - Stack Overflow
There is no guaranteed unique id for emails, the Message-ID is about as close as you come. The best you can actually hope for is unique for the server...and even that depends upon the type of mail server and what it does.

Unique ID in IMAP protocol
Unique ID in IMAP protocol

RFC 3501 (https://www.limilabs.com/mail/rfc/3501) specification says:

“2.3.1.1. Unique Identifier (UID) Message Attribute

A 32-bit value assigned to each message, which when used with the unique identifier validity value (see below) forms a 64-bit value that MUST NOT refer to any other message in the mailbox (folder) or any subsequent mailbox (folder) with the same name forever. Unique identifiers are assigned in a strictly ascending fashion”

“The unique identifier of a message MUST NOT change during the session, and SHOULD NOT change between sessions.”

“Any change of unique identifiers between sessions MUST be detectable using the UIDVALIDITY mechanism”

“The unique identifier validity value is sent in a UIDVALIDITY response code in an OK untagged response at mailbox (folder) selection time.”

Larch - a tool to copy messages from one IMAP server to another
Note: I no longer actively develop or use Larch, so it is effectively unmaintained. Many people claim it still works well for them, so feel free to use it, but please don't expect support, bug fixes, or new features.

Larch is a tool to copy messages from one IMAP server to another quickly and safely. It's smart enough not to copy messages that already exist on the destinati

Courier worksheet
For scalability, we are going to arrange for exim to deliver all local mail in Maildir format. This creates a subdirectory called "Maildir" in the user's home directory, which in turn contains three subdirectories: new, cur and tmp. Messages are written into tmp, moved to new when delivery is complete, and moved to cur when read. Each message has a long unique filename based on the hostname and the time of day.

Because each message is stored in a separate file, it is much faster for the pop3 daemon to start up every time a user connects. It also allows for safe delivery onto a shared (NFS) disk backend.

Exim does not include any software for retrieving mail from a mailbox, so we need to install additional software. Courier is a mail system which includes a number of packages. In fact it has its own MTA, but we will ignore this (it is still under heavy development, and does not have the flexibility needed for an ISP environment). The components we are interested in are the IMAP/POP3 servers and 'sqwebmail', the webmail server.

You can get the entire courier system as one package (including the MTA), or just the components. We will get the authlib, pop3/imap and webmail components separately.

Remember: in the command examples given below, commands shown with the prompt "$" should be run as your normal non-root userid. Only those commands with prompt "#" need to be run as root.

IMAP clients
Ok, attached is the list of unique-ish FETCH commands that we use to match on. They probably don't match what the client sends exactly (our logging is based on our parsing of the fetch, not on the direct client text, and then we further munge to generize the line some more, hence <chunk.chunk> and <0.chunk>). ---- Its also focused more on the state of clients ~3-4 years ago, with the uptick in usages of the ID command and the overwhelming numbers of a small set of clients, we haven't really kept it up to date. ---- Posted on Aug 2, 2012.
