Order in which UIDs are assigned..

[Akash]

Hi,

I just want some clarification on how Dovecot's IMAP assigns UIDs when 
it picks files from the "new" directory of a Maildir. What I am 
observing is that only ctime has a role to play in it. For example if 
there are two files in "new", a.msg & z.msg. Even when a.msg has lower 
mtime than z.msg and "a" comes before "z" alphabetically, dovecot will 
assign z.msg a lower UID if its ctime is lower than a.msg. Is this 
correct?

Secondly, when mails are placed into Maildir through a external 
mechanism by-passing LDA, by any means is it possible for IMAP to run 
seive on it when it migrates the files from new to cur and indexes them? 
I understand that this might not be a valid question as mail is 
delivered already so there is nothing to filter :-)
