What's the message's UID in the message storage of cyrus imapd.

[Penghui Wang <wangpenghui@xxxxxxxxx>]

Hi,

 

In the document of cyrus imapd package, there are something describe the message files in the message storage.

 

message files

There is one file per message, containing the message in RFC 822 format. Lines in the message are separated by CRLF, not just LF. The file name of each message is the message's UID followed by a dot (.).

 

I have googled for a while, but have got anything useful to explain what is the message's UID.

 

Could someone pick me up?

 

Thanks very much.
