Maildir-based IMAP server broke (Score 3, Informative)

My ISPs IMAP server broke. It used the maildir format and got *really* confused with file names like:

% ls -tr | tail
999878615.18243.pop.xxx.com:2,S*
999882709.76833.pop.xxx.com:2,RS*
999883989.13343.pop.xxx.com:2,S*
999900385.97510.pop.xxx.com:2,S*
999906796.21947.pop.xxx.com:2,S*
999914926.66179.pop.xxx.com:2,S*
999922220.49590.pop.xxx.com:2,S*
999975475.10798.pop.xxx.com:2,S*
1000040737.72591.pop.xxx.com:2,S*
1000062814.85554.pop.xxx.com:2,*

I think it was an old version of uw-imapd with maildir patches.

I wrote a short script to rename all files created before 1,000,000,000 with a leading zero. The resulting file names with "09*" fixed the problem!
