[Dovecot] dovecot-uidlist: Duplicate file entry at line

[Luca Palazzo]

Hi Timo,
I tried the patch and duplicate uid are always there.

Look at this:

It seems that LMTP process duplicate UID or something related to it. 
But, duplicate occurs sometime during LMTP delivery and sometime after 
LMTP delivery with IMAP or POP3.

I hope this helps.
