Message UID

[Egoitz Aurrekoetxea]

Good afternoon,

I have a question. When you do unexpunge -lv on a mailbox and obtain the UID of the messages… that UID does correspond with the mail corresponding file in the mailbox?. I mean 
If I want to perform some action with a deleted (but not at that moment expunged) mail in a mailbox… how could I know it’s file name?. I’m running Cyrus 2.3.18.

Best regards,
