Hi,

I am having problems running courier-imap on Coda.
When running versions of courier-imap higher than 1.6.1 on Coda (ex. 1.7.0, 
especially when moving/deleting messages through any imap client), I always 
got inconsistencies with files like courierimapuiddb and pop3dsizelist.
I read about Coda having problems with link() and someone recommended using 
rename() instead.
So I looked in the code in courierimap 1.6.1 and found one instance of link() 
in liblock/mail.c. Changing link() to rename() seemed to have fixed a lot of 
problems for a while. POP3 clients no longer got error messages like "IMAP 
Server replied: No such file or directory" and other weird errors. IMAP also 
looked like it worked fine. Then I started playing with IMAP_EMPTYTRASH and it 
worked for a week or so and again inconsistencies and problems with the 
courierimapuiddb file. pop3dsizelist is not a problem anymore however.

Do you have any suggestions? Do you think this could be related to the change 
I made in liblock/mail.c ?
Any help would be greatly appreciated. I attached some info from the coda logs 
and checkup with coda's repair tool to see which files where accessed/altered. 
hope it helps.

Respectfully,
Tim Hasson
